[Bug 480571] New: Octave can't compile mex file

https://bugzilla.novell.com/show_bug.cgi?id=480571 Summary: Octave can't compile mex file Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: i586 OS/Version: openSUSE 11.1 Status: NEW Severity: Normal Priority: P5 - None Component: Other AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: ivan.sutoris@gmail.com QAContact: qa@suse.de Found By: --- User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.6) Gecko/2009012700 SUSE/3.0.6-0.1.2 Firefox/3.0.6 I am using Octave 3.0.3-4.1 from Contrib repository. When I use it to compile a mex file, I get following error: In file included from /usr/include/octave-3.0.3/octave/mexproto.h:61, from /usr/include/octave-3.0.3/octave/mex.h:77, from mextest.c:1: /usr/include/octave-3.0.3/octave/mxarray.h:49:19: error: cstring: No such file or directory This seems to be caused by including cstring header (which is valid for C++ only) when Octave compiles mex file with gcc. This specific include statement (at line 49 of mxarray.h) comes from patch to mxarray.h.in applied during packaging, so I believe this bug is distro-specific. After bit searching, I've found that similar problem occured in Fedora [1]. When I change line 49 of mxarray.h from #include <cstring> to #include as mentioned in comments to Fedora bug, problem goes away (however I don't know if this is correct solution in general). [1] https://bugzilla.redhat.com/show_bug.cgi?id=435600 Reproducible: Always Steps to Reproduce: Example mex file from Octave manual: #include "mex.h" void mexFunction (int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[]) { mxArray *v = mxCreateDoubleMatrix (1, 1, mxREAL); double *data = mxGetPr (v); *data = 1.23456789; plhs[0] = v; } Save the code to file (e.g. mextest.c) and compile in Octave with "mex mextest.c", or outside Octave with "mkoctfile --mex mextest.c" Actual Results: In file included from /usr/include/octave-3.0.3/octave/mexproto.h:61, from /usr/include/octave-3.0.3/octave/mex.h:77, from mextest.c:1: /usr/include/octave-3.0.3/octave/mxarray.h:49:19: error: cstring: No such file or directory Expected Results: Octave should create compiled mex file. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
