AFAIK, it's probably the first time the "octave sjlj >exception issue" has appeared in this list. As far as I've seen, this is a >gcc issue. Disscussion seem to be started from the foloowing points http://gcc.gnu.org/ml/gcc-bugs/2004-03/msg01605.html And also cygwin.com http://cygwin.com/ml/cygwin/2005-04/msg01070.html In 2.1.xx series, I have built octave by myself using gcc-3.2 from special web site. For octave 2.9.xx, the gcc-3.2 is no longer to be used. So I have built gcc-3.4.4 --disable-sjlj-expceptions ******************** $/opt/octave-2.9.13/gcc-3.4.4d/bin/gcc -v Reading specs from /opt/octave-2.9.13/gcc-3.4.4d/lib/gcc/i686-pc- cygwin/3.4.4/specs Configured with: /home/gcc_s/gcc-3.4.4-3/gcc-3.4.4-3/configure -- disable-sjlj-exceptions --prefix=/opt/octave-2.9.13/gcc-3.4.4d Thread model: single gcc version 3.4.4 (cygming special, gdc 0.12, using dmd 0.125) ******************** >The cygwin octave maintainer (if [s]he is still there) must know more about >this. However, Cygwin's octave is 2.1.72 but mainline is 2.9.13. James R. Phillips was the maintaner of the octave-2.1.73 on cygwin. However there are noresponses for my binary upload to on my web. Perhaps he is not working as a maintainer. At that time, the Octave only be built using the cygwin on the windows. So I suppose that he knows the problem but build it by the normally prepared compiler. >Would it be possible for you to send corresponding straces of the cases you >posted below? > For Octave on mingw octave.exe:1> testOregoB ans = 1.5781 $ gcc -v Reading specs from c:/Programs/MinGW/bin/../lib/gcc/mingw32/3.4.2/ specs Configured with: ../gcc/configure --with-gcc --with-gnu-ld --with-gnu- as --host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads -- disable-nls --enable-languages=c,c++,f77,ada,objc,java --disable-win32 -registry --disable-shared --enable-sjlj-exceptions --enable-libgcj -- disable-java-awt --without-x --enable-java-gc=boehm --disable-libgcj- debug --enable-interpreter --enable-hash-synchronization --enable- libstdcxx-debug Thread model: win32 gcc version 3.4.2 (mingw-special) Tatsuro Matsuoka -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
