Hello, building gcc version 4.5.2 (with C, C++, Fortran) I get the build error libtool: compile: /home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2_build/./gcc/gfortran -B/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2_build/./gcc/ -B/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.5.2/x86_64-unknown-linux-gnu/bin/ -B/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.5.2/x86_64-unknown-linux-gnu/lib/ -isystem /home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.5.2/x86_64-unknown-linux-gnu/include -isystem /home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.5.2/x86_64-unknown-linux-gnu/sys-include -DHAVE_CONFIG_H -I. -I/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2/libgfortran -iquote/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2/libgfortran/io -I/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2/libgfortran/../gcc -I/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2/libgfortran/../gcc/config -I../.././gcc -D_GNU_SOURCE -I . -Wall -Werror -fimplicit-none -fno-repack-arrays -fno-underscoring -fallow-leading-underscore -g -O2 -c /home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2/libgfortran/intrinsics/f2c_specifics.F90 -o f2c_specifics.o >/dev/null 2>&1 /bin/sh ./libtool --tag=CC --mode=link /home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2_build/./gcc/xgcc -B/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2_build/./gcc/ -B/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.5.2/x86_64-unknown-linux-gnu/bin/ -B/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.5.2/x86_64-unknown-linux-gnu/lib/ -isystem /home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.5.2/x86_64-unknown-linux-gnu/include -isystem /home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.5.2/x86_64-unknown-linux-gnu/sys-include -std=gnu99 -Wall -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -Wextra -Wwrite-strings -fcx-fortran-rules -ffunction-sections -fdata-sections -g -O2 -o libgfortran.la -version-info `grep -v '^#' /home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2/libgfortran/libtool-version` -no-undefined -bindir "/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.5.2/bin" -lm -Wl,--version-script=/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2/libgfortran/gfortran.map -rpath /home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/Installations/Gcc/4.5.2/lib/../lib64 backtrace.lo bounds.lo compile_options.lo convert_char.lo environ.lo error.lo fpu.lo main.lo memory.lo pause.lo stop.lo string.lo select.lo all_l1.lo all_l2.lo all_l4.lo all_l8.lo all_l16.lo any_l1.lo any_l2.lo any_l4.lo XXX many more of these XXX make[4]: execvp: /bin/sh: Argument list too long make[4]: *** [libgfortran.la] Error 127 make[4]: Leaving directory `/home/csoliver/SAT-Algorithmen/OKplatform/ExternalSources/builds/Gcc/gcc-4.5.2_build/x86_64-unknown-linux-gnu/libgfortran' I know that with newer Linux versions longer command lines are possible. However I wonder whether I really have to upgrade my operating system (right now)? I'm running bash in a recent version > /bin/sh --version GNU bash, version 3.2.48(1)-release (x86_64-unknown-linux-gnu) Copyright (C) 2007 Free Software Foundation, Inc. Also binutils are up-to-date. But this doesn't help. Is there some flag? xargs-usage in the makefiles would also apparently solve the problem. I'll try it now with cleaned environment (perhaps I'm lucky). Sooner or later I have to upgrade the operating system, but right now it would be good of there would be some other method (deadlines are waiting). Thanks in any case! Oliver
