| Summary | 0001090: recursive reference to CXXFLAGS in pdf module | ||||
| Description | My make refuses to compile the pdf module due to a recursive reference of CXXFLAGS. The problem is at this place in the Makefile: # gcc 3.3 produces BROKEN code for -O1 and -O2 (PDF extraction # would fail silently) hence we MUST override the user flag here # which may contain -O1 or -O2! CXXFLAGS = "`echo "$(CXXFLAGS)" | sed -e "s/-O?//g"` -O0" Calling make yields the following error message: Makefile:436: *** Recursive variable `CXXFLAGS' references itself (eventually). Stop. Since I use gcc 4.0.2, I simply commented this line out and then the compilation works. | ||||

Suggested fix: Compile using the flags in LIBEXT_PDF_CXXFLAGS, which would be defined as: LIBEXT_PDF_CXXFLAGS = "`echo "$(CXXFLAGS)" | sed -e "s/-O?//g"` -O0" Thus avoiding recursion... |

I guess causing problems in recent systems to work around legacy problems that few people have is a bad idea. Also, the C++, xpdf-based PDF extractor will die sooner rather than later anyway. For now, I've removed the CFLAGS-hack and instead put a note into PLATFORMS. |
