Compile Error on Linux

Hi there.

I successfully installed a postgre system on a Sun Solaris .. it run's fine .. now I tried to install another one on a Linux 2.0.32 System with gcc 2.8.0 and postgre6.4

I have Flex installed (2.5.4) and Bison .... but I get the following error when doing a make all:

make[3]: Leaving directory `/usr/src/pgsql/src/interfaces/ecpg/preproc'
make[2]: Leaving directory `/usr/src/pgsql/src/interfaces/ecpg'
make -C libpq++ all
make[2]: Entering directory `/usr/src/pgsql/src/interfaces/libpq++'
c++ -I../../backend -I../../include -I../../interfaces/libpq -I../../include -I../../backend -O2 -Wall -Wmissing-prototypes -fpo
In file included from pgenv.cc:23:

make[2]: *** [pgenv.o] Error 1
make[2]: Leaving directory `/usr/src/pgsql/src/interfaces/libpq++'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/usr/src/pgsql/src/interfaces'
make: *** [all] Error 2
postgres(at)ferengi:/usr/src/pgsql/src >

anyone an idea?
