how create a shared library? #4
Comments

with gcc it works: $ gcc -Dlphobos2_EXPORTS -DDMDV2 -DIN_LLVM -D_DH -DOPAQUE_VTBLS -DPOSIX -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -fPIC -shared *.o -o liblocalization.sowith llvm-ld llvm-ar exist too never used |
|
Does this need druntime & rc lib building with PIC ? |
|
you can try it is the better thing :-) . |
|
if is a lib you need use flag: -link-as-library |
|
just for update this topic, for generate a shared lib with llvm-ld they are several step: $ ldc2 --output-bc --output-o -op -release -c -relocation-model=pic -od=../build *.dllvm bytecode finish with .bc and are in ../build directory $ cd ../buildMerge llvm bytecode together in one $ lvm-ld -link-as-library -o libDparser.bc -L/usr/local/lib64/ -L/usr/lib64 -ldruntime-ldc -llphobos2 -lm -ldl -lrt -soname=Dparser *.bcrun llc $ llc -relocation-model=pic libDparser.bcEnd the process by build shared lib $ gcc -shared libDparser.s -o libDparser.so |

The test checks the stack frame of `_Dmain` is in the backtrace, however if unused locals are optimised out and`test` is inlined into `main`
```d
void test()
{
int innerLocal = 20;
throw new Exception("foo");
}
void main(string[] args)
{
string myLocal = "bar";
test();
}
```
then the point at which the untapped exception is thrown is at the start of D main - not somewhere in the middle of it - and so GDB prints
```
...
#4 D main (args=...)
```
rather than
```
...
#4 0xSOMEADDRESS in D main (args=...)
```

2/ create a shared library
In which lib are define these thing?
2/ create a static lib is easy
