I tried: DEB_BUILD_OPTIONS='noopt,nostrip' debuild -us -uc An example gcc command line is: gcc -DHAVE_MKSTEMP -DHAVE_HYPOT -DHAVE_FILE64 -DHAVE_MKSTEMP64 -DHAVE_FONTCONFIG -DHAVE_LIBIDN -DHAVE_SETLOCALE -fPIC -O2 -Wall -Wstrict-prototypes -Wundef -Wmissing-declarations -Wmissing-prototypes -Wwrite-strings -Wno-strict-aliasing -Wdeclaration-after-statement -fno-builtin -fno-common -DHAVE_STDINT_H -DGX_COLOR_INDEX_TYPE="unsigned long int" -g -O2 -g -O2 -fPIC -DUSE_LIBPAPER -DGS_DEVS_SHARED -DGS_DEVS_SHARED_DIR=\"/usr/lib/ghostscript/9.01\" -I./psi -I./obj -I./obj -I./base -o ./obj/zcharout.o -c ./psi/zcharout.c (so no -O0) in the end: debian/tmp/usr/bin/gs: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, not stripped but: debian/libgs9/usr/lib/libgs.so.9.01: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped so there's not much I can do. > > If the latter, please note that this package uses CDBS which abstracts > away those ifdef's (else it possibly means that not ghostsctript but > cdbs is broken!) > > > >so I've tried rebuild manually using tips from another bug report, but: > > > >configure: WARNING: unrecognized options: --enable-debug > > Yeah - ghostscript only uses limited autotools features, so that one > doesn't surprise me.
