Syntax error from configure script when trying to compile OpenModelica

[nils.henkel@…]

I am trying to compile OpenModelica on RedHat 6.7

Procedure:
1.) Clone from GitHub:
$ git clone --recursive ​https://github.com/OpenModelica/OpenModelica.git

2.) Compilation according to README.md:
$ autoconf
$ ./configure CC=clang CXX=clang++
[...]
checking whether we are using the GNU Fortran compiler... yes
checking whether gfortran accepts -g... yes
./configure: line 4162: syntax error near unexpected token `fi'
./configure: line 4162: `fi'
configure: error: ./configure failed for OMCompiler

Since the full output is long, I am attaching 'openmodelica-compilation.txt' which contains my full output.

Thanks,
Nils

You need to use a non-German locale to attach files to a Trac system. I would need the OMCompiler/configure file to see which line is wrong (it is generated by your system's autoconf).

Thanks. I am attempting now to attach the generated configure script.

Hi,

if anyone could help, it would be much appreciated.

This is the configure file for OpenModelica, not OMCompiler.

[nils.henkel@…]

Right. Turns out that was why I did not understand the error myself. I am attaching the correct configure script. In that one, the syntax error is obvious. After I fixed that manually, I could run the configuration.

OMCompiler configure script

So it's an old autoconf that likes to emit bad code. Newer autoconf handles empty statements fine :)

I suppose the following should make it work fine and avoid the manual tweaking of configure:

configure.ac

     CPPFLAGS="$CPPFLAGS -I$withval/$MINGWNUM/include -I$withval/$MINGWNUM/include/tre"

Thanks a lot, that solved this problem!
