So this appears to be icc pretending to be gcc (in order for the slim_* to be defined to something) and then not implementing the attributes it just declared it had. If you can extend the checks in cairo-compiler-private.h, e.g.: #if __GNUC__ >= 3 && defined(__ELF__) && !defined(__sun) to work for you (and everybody else), we will happily take a patch. The problem is that : #if __GNUC__ >= 3 && defined(__ELF__) && !defined(__sun) is true even when compiling with icc. To fix the problem you can suppress or comment everthing between #if __GNUC__ >= 3 && defined(__ELF__) && !defined(__sun) and #else Idwakest -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Created attachment 15135 [details] Warning and error output of intel Compiler (make test after a make clean) cairo compiles without an problem but the test suit and all applications fail with undefined reference warnings. I track down this to this warnings from the compiler: cairo.c(3434): warning #1358: declaration aliased to undefined entity "INT_cairo_status" slim_hidden_def (cairo_status); ^ cairo.c(3238): warning #1358: declaration aliased to undefined entity "INT_cairo_get_matrix" slim_hidden_def (cairo_get_matrix); ^ cairo.c(3151): warning #1358: declaration aliased to undefined entity "INT_cairo_get_current_point" slim_hidden_def(cairo_get_current_point); ^ cairo.c(3084): warning #1358: declaration aliased to undefined entity "INT_cairo_get_tolerance" slim_hidden_def (cairo_get_tolerance); ^ The compiler produce a lot of this warning's and the resulting lib is not usable. Gcc 4.3 compile the same source witout any problem. if tried without Optimization flags without success. icc version: icc (ICC) 10.1 20080212
