When port is about to be compiled on a platform with most recent (proposed as of this moment) nVidia driver 367.27 (please see PR 201340 and there the latest patch as of today, 22nd Juno of 2016), the port fails to compile compalining about the error/missing shown below: [...] /usr/local/lib/libnvidia-glcore.so.1: undefined reference to `nv_vasprintf_alloc' /usr/local/lib/libnvidia-glcore.so.1: undefined reference to `nv_vasprintf_free' /usr/local/lib/libnvidia-glcore.so.1: undefined reference to `nv_vasprintf_vsnprintf' cc: error: linker command failed with exit code 1 (use -v to see invocation) gmake[5]: *** [Makefile:477: kms-steal-crtc] Error 1 gmake[5]: *** Waiting for unfinished jobs.... /usr/local/lib/libnvidia-glcore.so.1: undefined reference to `nv_vasprintf_alloc' /usr/local/lib/libnvidia-glcore.so.1: undefined reference to `nv_vasprintf_free' /usr/local/lib/libnvidia-glcore.so.1: undefined reference to `nv_vasprintf_vsnprintf' cc: error: linker command failed with exit code 1 (use -v to see invocation) gmake[5]: *** [Makefile:481: kms-universal-planes] Error 1 gmake[5]: Leaving directory '/usr/ports/graphics/libdrm/work/libdrm-2.4.66/tests/kms' gmake[4]: *** [Makefile:849: all-recursive] Error 1 gmake[4]: Leaving directory '/usr/ports/graphics/libdrm/work/libdrm-2.4.66/tests' gmake[3]: *** [Makefile:809: all-recursive] Error 1 gmake[3]: Leaving directory '/usr/ports/graphics/libdrm/work/libdrm-2.4.66' gmake[2]: *** [Makefile:568: all] Error 2 gmake[2]: Leaving directory '/usr/ports/graphics/libdrm/work/libdrm-2.4.66' ===> Compilation failed unexpectedly.
The problem is caused by a bug in one of the driver's libraries of x11/nvidia-driver when BLOB is set to revision > 364.19 (i.e. 367.27). The problem does not appear if 364.19 has been chosen. It further seems that the problem has to be solved by nVidia themselfes and is not a fault of the port. I'm closing this PR.
