I want to run my Haskell program which I've compiled on other computer, so I try: $ ./eternitypar ./eternitypar: error while loading shared libraries: libgmp.so.10: cannot open shared object file: No such file or directory $ LD_PRELOAD=./libgmp.so.10 ./eternitypar ./eternitypar: /lib/libc.so.6: version `GLIBC_2.7' not found (required by ./libgmp.so.10) $ LD_PRELOAD=./libc.so:./libgmp.so.10 ./eternitypar ERROR: ld.so: object './libc.so' from LD_PRELOAD cannot be preloaded: ignored. ./eternitypar: /lib/libc.so.6: version `GLIBC_2.7' not found (required by ./libgmp.so.10) $ LD_PRELOAD=./ld-linux.so.2:./libc.so:./libgmp.so.10 ./eternitypar ERROR: ld.so: object './ld-linux.so.2' from LD_PRELOAD cannot be preloaded: ignored. ERROR: ld.so: object './libc.so' from LD_PRELOAD cannot be preloaded: ignored. ./eternitypar: /lib/libc.so.6: version `GLIBC_2.7' not found (required by ./libgmp.so.10) So I download a package from http://new-www.haskell.org/ghc/download_ghc_7_0_1#x86_64linux and I try: $ ./configure checking for path to top of build tree... utils/ghc-pwd/ghc-pwd: error while loading shared libraries: libgmp.so.3: cannot open shared object file: No such file or directory configure: error: cannot determine current directory Why is it looking for such an old version, when 7.0.1 should be up-to-date? But fine, I can replace ghc-pwd with symlinked /bin/pwd, but I have a problem with some pgcc installed on the machine, so I run ./configure --with-gcc=/usr/bin/gcc: (/usr/bin/gcc exists and works) checking for path to top of build tree... /u/gar061/tmp/ghc-7.0.1 checking for perl... /usr/bin/perl checking if your perl works in shell scripts... yes checking for a BSD-compatible install... /usr/bin/install -c checking whether ln -s works... yes checking for ar... /usr/bin/ar checking whether /usr/bin/ar is GNU ar... yes checking for ar arguments... q checking for gcc... /tools/pgi725/linux86-64/7.2-5/bin/pgcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C compiler... no checking whether /tools/pgi725/linux86-64/7.2-5/bin/pgcc accepts -g... yes checking for /tools/pgi725/linux86-64/7.2-5/bin/pgcc option to accept ISO C89... none needed checking whether ranlib is needed... no checking for sed... /bin/sed configure: error: gcc is required It's ignoring my choice of GCC. Installation of 6.12.3 runs the same way. Then I move to compilation from source codes, but here - http://new-www.haskell.org/ghc/download_ghc_7_0_1#sources - I read: "The source distribution needs an installed GHC (version 6.10 at least)." Oh, so I need the application to build the application? What's the reason? Is there any other way to make it work? Thanks, Ondřej Garncarz
