Description Will Newton 2001-02-07 00:16:17 UTC

Code using the plib headers (plib, Powertools) will not compile.

Errors are:

c++ -DPACKAGE=\"plib_examples\" -DVERSION=\"1.1.8\" -DHAVE_LIBGL=1 
-DHAVE_LIBGLU=1 -DHAVE_LIBGLUT=1 -DSTDC_HEADERS=1 -DHAVE_GL_GL_H=1 
-DHAVE_GL_GLUT_H=1 -DHAVE_PLIB_SG_H=1 -DHAVE_PLIB_SL_H=1

-DHAVE_PLIB_JS_H=1 -DLINUX_JOYSTICK_IS_PRESENT=1  -I. -I.      -g -O2 -O6

There seem to be similar issues with other includes (mimelib).
Looks like it may be a preprocessor problem?

Comment 1 Jakub Jelinek 2001-02-07 00:28:49 UTC

This is fixed in cpp-2.96-74 (basically new cpp was not honoring
NO_IMPLICIT_EXTERN_C define, so all /usr/include headers had implicit
extern "C").
