Hello, I just tried to compile the SVN head of matplotlib (r4994) from source on OS X 10.5.2 (with source builds of python 2.5.2 and the SVN head of numpy), and ran into an "internal compiler error" in the agg code. (pkgconfig 0.23 and wxPython 2.8.7.1 also present and accounted for.)
Here's the compile line and error: > building 'matplotlib.backends._backend_agg' extension > gcc -fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused- > madd -fno-common -dynamic -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict- > prototypes -I/Library/Frameworks/Python.framework/Versions/2.5/lib/ > python2.5/site-packages/numpy/core/include -I/usr/X11/include/ > libpng12 -I/usr/local/include -I/usr/include -I/usr/X11R6/include - > I. -I/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/ > site-packages/numpy/core/include -Isrc -Iagg24/include -I. -I/usr/ > X11/include/freetype2 -I/usr/X11/include -I/usr/local/include -I/usr/ > include -I/usr/X11R6/include -I. -I/Library/Frameworks/ > Python.framework/Versions/2.5/include/python2.5 -c src/_image.cpp -o > build/temp.macosx-10.4-i386-2.5/src/_image.o > cc1plus: warning: command line option "-Wstrict-prototypes" is valid > for C/ObjC but not for C++ > src/_image.cpp: In member function ‘Py::Object > _image_module::from_images(const Py::Tuple&)’: > src/_image.cpp:842: error: insn does not satisfy its constraints: > (insn 2573 1070 2574 126 agg24/include/agg_color_rgba.h:268 (set > (mem:QI (plus:SI (reg/f:SI 6 bp) > (const_int -280 [0xfffffffffffffee8])) [0 SR.2969+0 > S1 A8]) > (reg:QI 5 di)) 56 {*movqi_1} (nil) > (nil)) > src/_image.cpp:842: internal compiler error: in > reload_cse_simplify_operands, at postreload.c:391 > Please submit a full bug report, with preprocessed source if > appropriate. > See <URL:http://developer.apple.com/bugreporter> for instructions. This seems to be an agg and OS X error; it's cropped up here: http://trac.osgeo.org/mapserver/ticket/2368 and John Hunter reported it on the agg list here: http://article.gmane.org/gmane.comp.graphics.agg/3963 Unfortunately, the error appears to either not have been fixed by the 10.5.1 update, as suggested in the email thread cited above, or the error re-appeared in 10.5.2. Changing the optimization flag from -O3 to -Os and compiling _image.cpp manually (along with copying src/_image.cpp to src/ image.cpp and compiling that manually in the same way) allowed me to finish building matplotlib, but clearly an optimized agg image library is pretty important... (-O2 didn't work...) Anyone have any idea at all about this error? Or is just turning off - O3 for this file the best thing to do until Apple fixes the compiler bug? Does anyone who knows more about agg than I want to try to reduce this to a test case?
