Hi,

I am trying to compile a C++ code (not mine) initially compiled on OSX, and I am trying to get it compiled on Ubuntu (11.04). I have absolutely no experience in C++, nor am I required to learn C++ (I usually do all my coding in Python)

The person I got the code from used a "Build script" to compile the code, opf which I need to convert to a linux compatible form. I've inserted the original build script below:

rm -f *.o
g++-mp-4.4 -c -O -m64 -Dintel_osx -I/usr/local/difmap2.4k/include splitc.cc
g++-mp-4.4 -o splitc splitc.o -L/usr/local/difmap2.4k/lib -lsphere -L/usr/local/difmap2.4k/lib -llogio -L/usr/local/difmap2.4k/lib -lpager -L/usr/local/difmap2.4k/lib -lcpgplot -L/opt/local/lib -lpng -lpgplot -L/usr/X11/lib -lX11 -L/usr/local/difmap2.4k/lib -lfits -L/usr/local/difmap2.4k/lib -lrecio -L/usr/local/difmap2.4k/lib -lscrfil -L/usr/local/difmap2.4k/lib -lslalib -ltecla -lcurses /opt/local/lib/gcc44/gcc/x86_64-apple-darwin11/4.4.6/libgcc.a      /System/Library/Frameworks/Foundation.framework/Versions/Current/Foundation      /System/Library/Frameworks/AppKit.framework/Versions/Current/AppKit -lm

Now here's my version for Ubuntu:

rm -f *.o
g++-4.5 -c -O -I/usr/local/uvf_difmap/include splitc.cc
g++-4.5 -o splitc splitc.o -L/usr/local/uvf_difmap/lib/libsphere -L/usr/local/uvf_difmap/lib/liblogio -L/usr/local/uvf_difmap/lib/libpager -L/usr/local/uvf_difmap/lib/libcpgplot -L/usr/lib/x86_64-linux-gnu/libpng -L/usr/lib/libpgplot -L/usr/lib/x86_64-linux-gnu/libX11 -L/usr/local/uvf_difmap/lib/libfits -L/usr/local/uvf_difmap/lib/librecio -L/usr/local/uvf_difmap/lib/libscrfil -L/usr/local/uvf_difmap/lib/libslalib -L/usr/local/uvf_difmap/libtecla -L/usr/lib/libcurses /usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.5/libgcc.a

Question: How do I run this "build script"? Searching on google gives me no help/information.

Since I did not know how to run the build script I decided to enter each line separately into the terminal, which did not work, but gave me the following errors:

hayden@roo:/usr/local/uvf_difmap/split_src$ sudo g++-4.5 -c -O -I/usr/local/uvf_difmap/include splitc.cc

Sorry for the long post, but I've exhausted all other options.

The Ubuntu version does not match the original. For example, -L/usr/local/difmap2.4k/lib -lsphere has different meaning than -L/usr/local/uvf_difmap/lib/libsphere Try this:

g++-4.5 -o splitc splitc.o -L/usr/local/uvf_difmap/lib/ -L/usr/lib/x86_64-linux-gnu -lsphere -llogio -lpager -lcpgplot -lpng -lpgplot --lX11 -lfits -lrecio -lscrfil -lslalib -ltecla -lcurses /usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.5/libgcc.a

As of what to do with the build script, make sure it has executable permissions, and just type its name at the command line.

Try this:

g++-4.5 -o splitc splitc.o -L/usr/local/uvf_difmap/lib/ -L/usr/lib/x86_64-linux-gnu -lsphere -llogio -lpager -lcpgplot -lpng -lpgplot --lX11 -lfits -lrecio -lscrfil -lslalib -ltecla -lcurses /usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.5/libgcc.a

Thanks for the suggestion, but I am getting the same error.
