Building doesn't work out of the box for v3.tar.gz or for github

building from github:

Makefile:1361: recipe for target 'arparse.o' failed
make[7]: *** [arparse.o] Error 1

error was too deep for me to understand, so I tried the following

building from the source archive provided on emilpro.com (v3)

Linking CXX executable emilpro

collect2: error: ld returned 1 exit status

it can be fixed with adding the following two lines to CMakeLists.txt (close to the bottom)

target_link_libraries(emilpro pthread)
target_link_libraries(tools/squash-instruction-models pthread)

so now I got a running build.

eventually the -pthread flag of g++ would be better?

Thanks for the report and sorry for not answering yet!

What system are you building under? The first error sounds like a dependency issue somehow. Anyway, I've been working on rewriting the GUI in QT for a long time, and that will really be the future version of emilpro - that one is built from the CMakeFiles.txt under src/qt/ instead. I don't think it will affect this issue though, but we should really aim to resolve it there.

Hi relascope,

You may be able to work around this issue by using:

cmake -DTHREADS_PREFER_PTHREAD_FLAG:INTERNAL=ON ..

I ran across this problem in a different project though so it may not be an exact fix

cheers
