Thank you very much for advice, it helped me :) Here is my
build.sh file after all experiments:
#!/bin/sh
swig -php speedup.i
dmd -m64 -fPIC -c -L-shared speedup.d
sed -i "1i char* d_speedUp(char* arg1);" speedup_wrap.c
gcc `php-config --includes` -fpic -c speedup_wrap.c
dmd -m64 -shared -defaultlib=libphobos2.so
-I/usr/lib/x86_64-linux-gnu speedup_wrap.o speedup.o
-ofspeedup.so
Note that we need to insert d_speedUp() function definition in
speedup_wrap.c file, otherwise there will be a warning "cast to
pointer" and segmentation fault when using compiled speedup.so
file:
speedup_wrap.c: In function ‘_wrap_d_speedUp’:
speedup_wrap.c:1141:12: warning: cast to pointer from integer
of different size [-Wint-to-pointer-cast]
Also I found no mention about rt_term() method in generated
files, so my php script works without it.
result = (char *)d_speedUp(arg1);
Great! This information might be valuable for others. If you want
and have the time, maybe you can write a short how-to article for
the wiki?
