problem when compiling GRASS against GEOS

[martinl]

Hi,

I have problem when compiling GRASS against GEOS library. Configuration fails with

configure:6376: checking for geos-config
configure:6424: checking for geos_c.h
configure:6432: gcc -E -I/usr/local/include  conftest.c >/dev/null 2>conftest.out
configure:6521: checking for initGEOS in -lgeos_c

/* Override any gcc2 internal prototype to avoid an error.  */
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char initGEOS();

int main() {
initGEOS()
; return 0; }

GEOS is configured with

./configure --prefix=/usr/local --enable-python --with-gnu-ld

Any idea? Thanks. Martin

Seems to be related to GEOSDelaunayTriangulation_r from geos_ts_c.cpp​

Did you run ./autogen.sh ?

martinl -- can you respond to this one

Replying to strk:

Did you run ./autogen.sh ?

Sorry, I overlooked this ticket. Right, closing.
