Re: [lwip-users] Can't compile unix unit tests using Cmake

[Dirk Ziegelmeier]

No, I having problems with that on Kubuntu 18.4, too. I'll disable the offending compiler flags to avoid problems in 2.1 release.

Hi,

I tried to compile the unix unit tests in debian stable and ubuntu
18.04 and in both cases I found that liblwipcore.a and
liblwipallapps.a are built correctly but trying to link lwip_unittests
fails with hundreds of "undefined reference" messages like these:

[100%] Linking C executable lwip_unittests

...

Trying with just "make check" works fine.
These are the steps I follow:

1 cd ports/unix/check/
2 mkdir build
3 cd build
4 cmake ..
5 make

I'm totally new to Cmake, am I doing something wrong?
