build fails

[ragnar76]

Hi there,

i went into some trouble building ParaTos. Output of GCC down below. I'm using Linux Mint 21.2 and gcc-12 (along with make, cmake, autoconf, automake and the other funky stuff)

[kelihlodversson]

Looks like some header include defines a global called _ or and later gnu C versions default to -fno-common which will not convert symbols like that to weak symbols and allow merging them.

Have you tried changing the compiler options to add -fcommon to work around the problem? (You can do it by adding -DCMAKE_C_FLAGS=-fcommon when running cmake.)

I had the same issue and "cmake .. -DCMAKE_C_FLAGS=-fcommon" did the job
