Wt

Ok, I've removed WT as best as I think I can.

I'm stepping through install instructions at: http://redmine.webtoolkit.eu/projects/wt/wiki/Installing_Wt_on_Ubuntu?version=33#Try-the-Examples

Asio = Good (as a far as I know).

Make install dies:

First round of make install took forever, with some signal depeciation message, then fails with errors. If I go through the cmake and make install again, I get:

How do I move forward please?

Also, even though I have installed Boot 1.55.0, it still finds and wants to use boost 1.46. I don't understand that.

I have also tried this section:

Installing from Prebuilt Packages

Since Wt 2.0.3, unofficial packages for Ubuntu are being built by Pau Garcia i Quiles. To install Wt, add the Wt PPA to your repositories (check "Adding this PPA to your system" in the Wt PPA page). After adding the repository to your system, run:

$ sudo apt-get update

$ sudo aptitude install libwt*

but no libwt* of any kind. I added the Pau Garcia I Quiles repository to my ubuntu build, but then when I run aptitude install libwt*, all hell breaks loose.

Maybe someone can tell me how to get the 'precise' version from Garcia's builds?

My head is going to explode; this info is so outdated.

Same problem here. I have CentOS 6 64-bit and installed boost-* with yum and have cmake 2.6+ but cannot find boost.

Hey,

What platform are you building on? Does it have enough memory, because I suspect this is a kill by the OS because running out-of-memory.

As a general advice for people with cmake problems:

1) Even if cmake ends with an error message, it will save its configuration in a file CMakeCache.txt. This is useful to see what is actually missing and what has been found.

2) This also means that if you rerun CMake, you should probably delete your current build directory and recreate it, since CMake will read the cache and only search for things previously not found. That may be confusing. For example if CMake found boost 1.46 and then after that you remove it in and install boost 1.55, it will be ignored until you delete your build and start over.

Ubuntu 12.04 32bit w/ 512MB of memory. The first attempt, it ran through (with a constant boost.signal depreciation error). But the second time, it stopped right at the error above.

I'd rather not go the compile route if I can avoid it. I wish I could figure out how to get the Garcia build.

Is there something more to do to remove what was installed through apt-get as well? I would love to remove everything WT related, as I'm not sure boost 1.55.0 is really installed either. And multithreading is the only reason I'm going through all this extra work.

I will kill the build directory and try again. I hope I don't need to re-image and start from scratch.

Thank you Koen!

I'm just going to keep on dropping things as I go.

I think I sorted out the boost version issue by updating cmake.findboost

But now I stop at 65% with:

c: internal compiler error: Killed (program cc1plus)

I tried greping for some indication of CssParser.o, but no result.

Per this thread though, it looks like I did run out of memory. And that is a drag, because I am excited to dig into WT. Also per that thread, would I be missing out if I backed up to version 3.3.0? In thread, the previous version does compile.

Thread referenced in above post: http://redmine.webtoolkit.eu/issues/2530

In file src/Wt/Render/CssParser.C, make sure that CSS_PARSER does not get defined (e.g. by commenting out line 11 of that source file).

PDF rendering will then not work.

BR,

Wim.

Per an answer on what looks like the mailing list, I comment out the CssParser line inside the CssParser.C (I think).

Also and unrelated, I cant cmake WGLWidgets because lack of gl and glew. So I apt-get what I found to be popular opengl libraries, but cmake still says no gl or glew.

I'm not going to be able to use WT, am I? Is there a way to get this going on 1/2 gig of memory? I need multithread, and the whole purpose will be for WEBGL dev, so it would be nice to know exactly which gl and glew is required for cmake.

Thank you!!

Or... How much memory will I need? I'm in a VPS style environment, so it's not like I can just pop in a few sticks of memory. But maybe I can work soemthing out temporary, if, memory is my problem.

Made it to 84% after setting up a swap file in Ubuntu.

In CMake.findboost, I appended to the additional versions, to include 1.55.0 1.55. I probably screwed it up by doing that. cmake liked it, but make did not.

Plus, I've installed every version of glew and gl I can find, and cmake just doesn't get it.

This has got to end soon...

I'm going to keep babbling on here since I need to resolve this. I think I understand these errors to be linker errors, at from what I've read. Does this have to do with any files in my build directory after cmake? or is this something that needs to be addressed before cmake?

I see advice such as: add -lboost_thread to the linking step. So what file do I add that to? Because make just goes; there is no step.

I ran cmake with -DWT_NO_BOOST_RANDOM=ON , make with VERBOSE=1.

Things are different now, and I stopped at 71%

I give up for tonight; I'm getting no where. Hopefully if this is fixable, this wall of text will be useful for someone else trying to install.

With respect to gl/glew: glew is included in Wt, you don't even have to install it. To know what you need for OpenGL, take a look at wt-x.y.z/cmake/WtFindGL.txt to see how Wt detects gl and glew. Check in your CMakeCache.txt to find out what cmake found and what's missing.

My guess about the link options is that the version of the boost .so files you link to does not correspond to the boost version of the header files you used to compile Wt. Header files are in /user/include/boost_1_55_0, but there's no special path set for libraries. If you compiled boost yourself, remove any standard installed libraries. You will have to remove your wt build directory completely and restart from an empty build directory to force cmake to re-detect boost. Again, verify in CMakeCache.txt to check if cmake found the correct boost libraries.

BR,

Wim.

Thank you Wim,

So if cmake tells me:

Boost version: 1.55.0

--- Found the following Boost libraries:

--- date_time

--- regex

--- program_options

--- signals

--- system

--- filesystem

--- thread

--- random

Consequently, I moved boost directories that wheren't 1.55 into a backup directory off of root, so hopefully they wouldn't be found. I don't know if that is good logic in a linux environment or not.

I need to make it known that all of this compiling and linking is like brain surgery or nuclear physics to me. Whatever you tell me will probably need to be dumbed down a few steps.

Like when you mention: "If you compiled boost yourself, remove any standard installed libraries." You might as well be talking Chinese, because I don't know what that means in relation to doing something to help get this installed. Ya, I don't know what that means. I appreciate the reply, but I don't know what that means.

I also had to add Boost 1.55 references to the cmake.findboost file, which is way out of the way of anything I am working on. And I'm also not sure I've done it correctly, or if I should've even don that. It seemed like an obvious choice though.

Thank you for your reply

So what boost paths do you see in CMakeCache.txt?

Wim.

I just did cmake -DBoost_DEBUG=ON -DBoost_USE_STATIC_LIBS=ON -DBoost_USE_MULTITHREADED=ON .. then ran make, and it stopped again but at 84%. Same errors pretty much.

Good question! A couple of examples from CMakeCache.txt:

//The Boost DATE_TIME library

Boost_DATE_TIME_LIBRARY:FILEPATH=/usr/lib/libboost_date_time-mt.so

//Boost date_time library (debug)

Boost_DATE_TIME_LIBRARY_DEBUG:FILEPATH=/usr/lib/libboost_date_time-mt.so

//Boost date_time library (release)

Boost_DATE_TIME_LIBRARY_RELEASE:FILEPATH=/usr/lib/libboost_date_time-mt.so

//The directory containing a CMake configuration file for Boost.

Boost_DIR:PATH=Boost_DIR-NOTFOUND

//The Boost FILESYSTEM library

Boost_FILESYSTEM_LIBRARY:FILEPATH=/usr/lib/libboost_filesystem-mt.so

Which are of course wrong. CMake says it got the version right though.

All the paths are wrong.

If you set BOOST_PREFIX to the right path, especially when you first run cmake in a clean build directory, and cmake still comes up with these libraries, that's a problem in cmake rather than in Wt. But afaik it does work if you set BOOST_PREFIX immediately right when running cmake for the first time.

CMake never forgets a library once it found it. So once it found the wrong ones, you're toast and the best thing to do is to remove your build directory completely. By uninstalling your system's cmake libraries (apt-get uninstall boost (I don't know the exact command)), you avoid that cmake can possibly find the wrong libraries to start with.

BR,

Wim.

So it's not as simple as manually updating CMakeCache.txt? Clean build directory is no problem; I've done that like 25 times now.

uninstalling your system's cmake libraries (apt-get uninstall boost (I don't know the exact command)) <--- sounds quite like I could destroy something, and will end up rebuilding the system. Do you mean uninstalling Cmake or Boost? I could try to redo them both

Thank you so much, I'm horrible with linux configuration outside of apt-get and this certainly falls outside the realm of WT. I greatly appreciate the help!!
