Hi,
I'm trying to compile a static one binary mono(Because the target system

First I got mono to build statically, but without libMonoPosixHelper in
the archive. After a few tries, I got also this, changed all
DllImport(MPH) calls in Mono.Posix.dll to DllImport("__Internal"), it
still gives me a TypeInitializationexception when I try to access the stat
symbol of the libMonoPosixHelper. With objdump I looked inside, the
symbols of libMonoPosixHelper are all inside the archive, so what am I
doing wrong?
Your custom loader is supposed to support dlopen(NULL) and
your linker must be able to export public symbols.
See ld's --export-dynamic option.

What platform is this? What kind of loader does your target system have? Does
it have any shared library loader?

DllImport("__Internal") requires that the target platform (1) support
dlopen(NULL, mode) to open the main executable, and (2) that dlsym() be able to
find symbols within the main executable.
Note that (1) is not true for Windows, so [DllImport("__Internal")] will not
work on Windows (iirc).

That's odd; Syscall.stat() P/Invokes Mono_Posix_Syscall_stat(), not stat():
https://github.com/mono/mono/blob/master/mcs/class/Mono.Posix/Mono.Unix.Native/Syscall.cs#L2851
Mono_Posix_Syscall_stat(), meanwhile, is just a simple wrapper around stat(2):
https://github.com/mono/mono/blob/master/support/sys-stat.c#L25
If your program is dying because Mono_Posix_Syscall_stat() can't be found, then
the problem is probably that dlopen(NULL, mode) is not supported on your
platform. If stat() can't be found, then (1) your platform doesn't provide
stat(2), or (2) (somehow) your program is being improperly linked and stat()
isn't being found.

Re: [Mono-dev] DllImport("__Internal") and libMonoPosixHelper static build
AFAIK, the DLLImport binding depend on loading information of dynamic
libraries, if you want to call something statically linked in the runtime
you'll need to move to using internal calls, but that means an extensive
rewrite of the the affected libraries both managed and native as the
protocol doesn't include automatic marshaling of managed types, and correct
versioning is a must to avoid crashes on incompatible ABIs.
Another possibility is to change the dynamic libraries binding mechanism to
search for statically linked symbols, not sure how complex this would be.
The best alternative is to fix the loader and keep the .so files around.
Just my two cents,

[Mono-dev] DllImport("__Internal") and libMonoPosixHelper static build
Hi,
I'm trying to compile a static one binary mono(Because the target system has
an incompatible loader).
First I got mono to build statically, but without libMonoPosixHelper in the
archive. After a few tries, I got also this, changed all DllImport(MPH)
calls in Mono.Posix.dll to DllImport("__Internal"), it still gives me a
TypeInitializationexception when I try to access the stat symbol of the
libMonoPosixHelper. With objdump I looked inside, the symbols of
libMonoPosixHelper are all inside the archive, so what am I doing wrong?
The script used to build: http://pastebin.com/t7dqdBYn
Regards
Ralph
