[gmx-developers] gmx CVS compile error

[Martin Dahlberg]

Hello,

Trying to compile from the CVS, downloaded today (14th Sept. 2005).
After bootstrapping and configure (--enable-float) I try to make but get
this error:

cc -DHAVE_CONFIG_H -I. -I. -I../../src -I/usr/X11R6/include
-I../../include -DGMXLIBDIR=\"/usr/local/gromacs/share/top\" -O3

pme.c:1732: error: (Each undeclared identifier is reported only once
pme.c:1732: error: for each function it appears in.)
make[3]: *** [pme.lo] Error 1
/.../

I have previously compiled the 3.3_beta_20050202 from CVS without problems.

Ideas?
