[Asterisk-video] Asterisk crash when using amr (app_h324m.so)

[Thomas Frieling]

Hi!

Just modified libh324m/src/Makefile like this:
CXXFLAGS = -DP_USE_PRAGMA -g3 -D_REENTRANT -O0 -Wall -fPIC -DPIC -DPTRACING
CFLAGS = -DP_USE_PRAGMA -g3 -D_REENTRANT -O0 -Wall -fPIC -DPIC -DPTRACING

This seems to work, but I get the following error:

[...]
g++ -o libh324m.so -shared h324m.o src/libh324m.a `ptlib-config --libs`
gcc -o test test.o -lh324m -L./ -lh324m

collect2: ld returned 1 exit status

libh324m.so is created anyway but makes asterisk crash like that:
asterisk: symbol lookup error: /usr/local/lib/libh324m.so: undefined symbol: _ZN11PASN_Object14SetConstraintsENS_14ConstraintTypeEij


Any ideas?
Thomas

Perhaps try:
CFLAGS=-g3 -pg -O0

I'm saw these settings in the Makefile of another app so I'm just
guessing here. During compilation you should see these settings in the
output so keep an eye on that. And you probably don't want to strip the
binaries (if you were even doing that at all).

Patrick
