Wt cmake Could NOT find Boost

Added by Gunnar Skogsholm over 3 years ago

I've used Wt successfully on Windows. It was great that you provided pre-built binaries. I'm also using vcpkg to build boost & various other 3rd party libraries.

Now, I'm building my project for Linux. Since Wt is built using cmake, I figured I could just add a reference to Wt in my cmake file. See attached file.

However, I'm having a lot of trouble: CMake Error at /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message): Could NOT find Boost

Any help would be greatly appreciated !

RE: Wt cmake Could NOT find Boost - Added by Gunnar Skogsholm over 3 years ago

My Conclusion:

  1. cmake is a clumsy, ill conceived technology, yet roughly works & provides some value
  2. vcpkg is a clumsy, ill conceived technology, yet roughly works & provides some value
  3. combining the two is non-functional

So, the right solution for me was to switch to using the vcpkg version of Wt

RE: Wt cmake Could NOT find Boost - Added by Gunnar Skogsholm over 3 years ago

Now, b/c of the tortured path I've chosen, I'm stuck trying to figure out the correct libraries to link to on Linux. Looking through the cmakefiles, but not finding a solid list.
On Windows, #pragmas took care of this

Any Help would be Greatly Appreciated!

RE: Wt cmake Could NOT find Boost - Added by Gunnar Skogsholm over 3 years ago

vcpkg has:

wt 4.5.0 Wt is a C++ library for developing web applications
wt[openssl] TLS support

In order to have SSL support, was I supposed to build the 2nd one?

RE: Wt cmake Could NOT find Boost - Added by Gunnar Skogsholm over 3 years ago

Thanks for all the help. I really appreciate it. For the record, for anyone else in vcpkg/boost/cmake hell, this is what worked for me:

RE: Wt cmake Could NOT find Boost - Added by Gunnar Skogsholm about 3 years ago

:) You all were such a great help last time, I thought I would "give back" & add the Windows equivalent of the above:

VS 16.9.1 -> Linker -> Input -> Additional Dependencies:

wthttpd.lib;wtd.lib;boost_program_options-vc140-mt-gd.lib;libhpdfd.lib;libssl.lib;boost_filesystem-vc140-mt-gd.lib;boost_regex-vc140-mt-gd.lib;boost_random-vc140-mt-gd.lib;libcrypto.lib;boost_thread-vc140-mt-gd.lib;zlibd.lib;boost_date_time-vc140-mt-gd.lib;libpng16d.lib;

RE: Wt cmake Could NOT find Boost - Added by Gunnar Skogsholm about 3 years ago

So, to summarize:

vcpkg doesn't generate the expected boost lib names, so I have modified line 477-9 of auto_link.hpp (file attached)

Examples of what I previously got by with: wthttpd.lib;wtd.lib; AND libssl.lib;libcrypto.lib;wtisapid.lib;wtd.lib;<

Based on that, I would guess that not all of these libs are required, but there is no price to including libs which are not needed.

from: wt 4.0ish, prebuilt binaries
to: wt 4.5, vcpkg build of wt & boost

Win Debug:
wthttpd.lib;wtd.lib;boost_program_options-vc140-mt-gd.lib;boost_filesystem-vc140-mt-gd.lib;boost_regex-vc140-mt-gd.lib;boost_random-vc140-mt-gd.lib;boost_thread-vc140-mt-gd.lib;boost_date_time-vc140-mt-gd.lib;libhpdfd.lib;libssl.lib;libcrypto.lib;zlibd.lib;libpng16d.lib;crypt32.lib

Release
wthttp.lib;wt.lib;boost_program_options-vc140-mt.lib;boost_filesystem-vc140-mt.lib;boost_regex-vc140-mt.lib;boost_random-vc140-mt.lib;boost_thread-vc140-mt.lib;boost_date_time-vc140-mt.lib;libcrypto.lib;libhpdf.lib;libssl.lib;zlib.lib;libpng16.lib;crypt32.lib

ISAPI -> replace wthttp.lib with wtisapi.lib:

wtisapid.lib;wtd.lib;boost_program_options-vc140-mt-gd.lib;boost_filesystem-vc140-mt-gd.lib;boost_regex-vc140-mt-gd.lib;boost_random-vc140-mt-gd.lib;boost_thread-vc140-mt-gd.lib;boost_date_time-vc140-mt-gd.lib;libhpdfd.lib;libssl.lib;libcrypto.lib;zlibd.lib;libpng16d.lib;crypt32.lib

wtisapi.lib;wt.lib;boost_program_options-vc140-mt.lib;boost_filesystem-vc140-mt.lib;boost_regex-vc140-mt.lib;boost_random-vc140-mt.lib;boost_thread-vc140-mt.lib;boost_date_time-vc140-mt.lib;libcrypto.lib;libhpdf.lib;libssl.lib;zlib.lib;libpng16.lib;crypt32.lib
