Package: nx-libs Version: HEAD Tags: Patch Found this problem while browsing: https://bugs.gentoo.org/show_bug.cgi?id=481360 Compiling nx-libs against jpeg-9a leads to a compilation error.

Specifically, it appears that jpeg-9a changed the definition for its "boolean" type from an int to some other type (bool in C++, it seems). Using TRUE and FALSE, as provided by the jpeg library, is what was done to address the problem. After applying the patch to HEAD (commit 0e3b414ea6ecb6cc359d3b95f5cfeb6096066139), Jpeg.cpp compiles fine. Configuration: Compiling against jpeg-9a. $ gcc -v Using built-in specs.

"git clone git://code.x2go.org/nx-libs.git" repository. 2. Change to the "nxcomp" directory. 3. Run "autoreconf" and then do "make Jpeg.o". Expected outcome: Successful compilation. Actual outcome: Compilation failure, see earlier in the report for the error messages.
