I have an ubuntu machine to run cura-build from the following doc.

Refer: https://github.com/Ultimaker/cura-build#ubuntulinux

My gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.5)

while running cmake command

I am getting this error,

~/ cura-build/build$ cmake …
cmake: /usr/lib64/tableausdk/libcurl.so.4: no version information available (required by cmake)
CMake Error at CMakeLists.txt:24 (get_filename_component):
get_filename_component unknown component CACHE

– Configuring incomplete, errors occurred!
See also “/cura-build/CMakeFiles/CMakeOutput.log”.
See also “/cura-build/CMakeFiles/CMakeError.log”.

In the CMakeError.log,

CMakeFiles/cmTC_2f3cc.dir/CheckSymbolExists.c.o: In function main': CheckSymbolExists.c:(.text+0x16): undefined reference topthread_create’
collect2: error: ld returned 1 exit status

File /cura-build/CMakeFiles/CMakeTmp/CheckSymbolExists.c:
/* */
#include <pthread.h>

int main(int argc, char** argv)
{
(void)argv;
#ifndef pthread_create
return ((int*)(&pthread_create))[argc];
#else
(void)argc;
return 0;
#endif
}

And also tried to compile gcc,

$ gcc -pthread
gcc: fatal error: no input files
compilation terminated.

Hi,

I am not sure how root is involved. Can you clarify?

Cheers,

Hi,
Now I resolved cmake issue by setting the CMAKE_PREFIX_PATH.
But I can’t able to run cura-build because of the CuraEngine seems to be an error.
How to resolve this?
/usr/local/lib/libArcus.so.1.1.0: undefined reference togoogle::protobuf::io::CodedInputStream::SetTotalBytesLimit(‌​int)’ collect2: error: ld returned 1 exit status CMakeFiles/CuraEngine.dir/build.make:98: recipe for target ‘CuraEngine’ failed CMakeFiles/Makefile2:142: recipe for target ‘CMakeFiles/CuraEngine.dir/all’ failed`

Again - you’re probably talking to the wrong people / forum here: this is ROOT, while you seem to try to build something based on Tableau.
