am instalat intai zlib
am instalatlibpng care foloseste zlib
am instalat gd
perl -i -p -e s/gd_jpg.o//g Makefile
make INCLUDEDIRS="-I. -I../zlib -I../libpng" LIBDIRS="-L../zlib -L.
-L../libpng" LIBS="-lgd -lpng -lz -lm" CFLAGS="-O -DHAVE_LIBPNG"
makeinstall
pana aici am facut la fel si mrtgul poate genera imagini *.png
am incercat sa generez si eu si da erorile alea
cand i-am dat la compilare:
gcc -o gd_ex gd.cc -L/usr/local/lib -lgd -I/usr/local/include
imi da alte erori legate de generarea pngurilor de genul:
************************************************
/usr/local/lib/libgd.a(gd_png.o)(.text+0x7c): In function `gdPngReadData':
: undefined reference to `png_get_io_ptr'
************************************************
asta inseamna ca nu isi gaseste librariile nu? dar de ce mrtgul stie sa le
gaseasca?
