Bug #81032 [NEW]: GD install is affected by external libgd installation

From: flaviohbatista at gmail dot com Operating system: MacOS PHP version: Irrelevant Package: GD related Bug Type: Bug Bug description:GD install is affected by external libgd installation Description: ------------ Description: When installing the GD extension using the bundled libgd, if any of the libraries used by libgd (e.g. libjpeg), are installed in a path that also happen to have a libgd installation, the extension code will include the external libgd files instead of the local ones. Example: 1. Assume that libjpeg is installed at /usr/local/include; 2. Assume that libgd is also installed at /usr/local/include; 3. The build system will add /usr/local/include to CFLAGS (through pkg-config) for libjpeg; 3. Once you run make, you may end up in an error referring to /usr/local/include/gd.h instead of the bundled gd.h. Root cause: The bundled libgd fork includes gd.h and other gd-specific header files using #include <foo.h> rather than #include "foo.h", which instructs the preprocessor to look for foo.h in the standard system directories and, if the file wasn't found, fall back to search in additional directories added to the search path. Reference: https://gcc.gnu.org/onlinedocs/cpp/Search-Path.html Solution: Replace #include <foo.h> with #include "foo.h", to ensure that the lookup will be executed in the local path first and then in the search path as fall back if the file was not found.
