hi list i try to execute a shell command (namely pdftk) from python/zope to fill out fdf forms in a pdf document this is my command, which is generated: pdftk /tmp/tmpRy0O_T.pdf fill_form /tmp/tmpz4mEG1.fdf output /tmp/tmpx1TxTD.pdf flatten the pdf and fdf files are temporary files i have a testcase which runs the surrounding method successfully (python only no zope), but wenn i access the method from zope it hangs when the pdftk command tries to write to the output files and i have to kill -9 the pdftk processes i've already tried with popen3, os.system etc. this problem does NOT occur on macos x, only on linux, for windows i don't know. my linux: Linux bd-pc 2.6.10-gentoo-r5 #2 Tue Jan 18 18:20:46 CET 2005 i686 Intel(R) Pentium(R) 4 CPU 2.00GHz GenuineIntel GNU/Linux is it possible that this is a gcj problem, because pdftk is java compiled with gcc? output of gcc -v Reading specs from /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/specs Configured with: /var/tmp/portage/gcc-3.3.5-r1/work/gcc-3.3.5/configure --enable-version-specific-runtime-libs --prefix=/usr --bindir=/usr/i686-pc-linux-gnu/gcc-bin/3.3.5 --includedir=/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/include --datadir=/usr/share/gcc-data/i686-pc-linux-gnu/3.3.5 --mandir=/usr/share/gcc-data/i686-pc-linux-gnu/3.3.5/man --infodir=/usr/share/gcc-data/i686-pc-linux-gnu/3.3.5/info --with-gxx-include-dir=/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.5/include/g++-v3 --host=i686-pc-linux-gnu --disable-altivec --enable-nls --without-included-gettext --enable-__cxa_atexit --enable-clocale=gnu --with-system-zlib --disable-checking --disable-werror --disable-libunwind-exceptions --enable-shared --enable-threads=posix --disable-multilib --enable-java-awt=gtk --enable-languages=c,c++,java Thread model: posix gcc version 3.3.5 (Gentoo Linux 3.3.5-r1, ssp-3.3.2-3, pie-8.7.7.1) thx in advance, bernd
