f77 compiler not found

[GoogleCodeExporter]

Hi, am attempting to compile and after install of gcc-gfortran version
4.4.1, I get error when compiling lbfgsb.f: 

make: f77: Command not found

Is there some way to tell Linux or GCC that the Fortran compiler is not f77? 

Thanks
Hal

hi, which linux distro. are you using?
try this slightly modified Makefile, it works on (some of) my 32bit machines.

Yet I couldn't managed to compile it on any 64bit machine, keep saying
src/NgramLM.cpp:XXX: undefined reference to 'void NgramModel::ApplySort<int>....

any luck out there?

Thanks for the suggestion.  I was using Debian 4.0, where it worked for both 32 
and 
64 bits.

NgramModel::ApplySort<T> is declared in NgramModel.h and defined in 
NgramModel.cpp.  
The particular template instantiations for ApplySort<int> and ApplySort<double> 
are 
further defined in NgramModel.cpp.  I hypothesize that the 64-bit compiler you 
are 
using does not fully support C++ templates.

Since I cannot reproduce your error, can you please try moving the template 
instantiations of ApplySort<int> and ApplySort<double> (NgramModel.cpp:812-817) 
to 
NgramModel.h:121?

Thanks.

Paul

I had the same problems with Debian 6.0 with gcc 4.4.5.

The compiler not found issue is resolved by using the suggested Makefile, or by 
using the autotools build system in revision 45. You have to install autoconf, 
automake and libtool to use this build system. Then issue
./autogen.sh --prefix=$(pwd)/usr
make
make install
to build mitlm.

The undefined reference issue is resolved by moving the template from the 
NgramModel.cpp to the NgramModel.h file. It should be fixed in revision 42.

Does revision 45 solves these issue for you too?
