Hello, I’m trying to build MEGAN3.2, using the command: ./make\_all\_programs.scr 32bit but has an error ‘NVFORTRAN-S-0023-Syntax error - unbalanced parentheses (readwrfcamx.f: 104)’, as the figure shows, I use pgfortan, Thank you for your help in advance. ![image](https://canada1.discourse-cdn.com/flex027/uploads/cmas/original/2X/c/c2a2bd1d75afe6e3812f107a3909fdca05ae3734.png) ---

The suspicion is that this is non-Standard “fixed 132” Fortran source. The compile-flag for this varies from compiler to compiler; I think it is `-Mextend` for PGI Fortran, unless nVidia have changed it. ---

Thank you for repley, I editd the Makefile as “PGF90 = pgf90 FCFLGS = -O -Mextend -Mlfs -Msecond\_underscore FCFLGS2 = -O -Mbyteswapio -Mextend -Mlfs -Msecond\_underscore FCFLGS3 = -O2 -Mnoframe -Mextend -Bstatic\_pgi LNKFLGS = -Bstatic\_pgi” then, it works
