[Mono-list] ICodeCompiler.CompileAssemblyFromSourceBatch failure

[Carl Cerecke]

Hi,

I have an unusual failure when calling
ICodeCompiler.CompileAssemblyFromSourceBatch. The compile works
correctly when called from a mono .exe, but does not when the same
.exe is called via the mono embedded calls.

This works on the command-line:
> mono mtest.exe

This code (using mono embedded libs) fails (never gets to printf):
int main(int argc, char *argv[]) {

    domain = mono_jit_init("mtest.exe");
    assembly = mono_domain_assembly_open (domain, "mtest.exe");
    mono_jit_exec(domain, assembly, argc, argv);
    printf("Ran mtest.exe\n");

The error message is:
Directory '/tmp/178d00f6' not found.

The successful CLI execution yeilds the strace (different run,
different tmpfile):
...
stat64("/tmp/437a94b0", 0xbf84c06c)     = -1 ENOENT (No such file or directory)
lstat64("/tmp/437a94b0", 0xbf84c06c)    = -1 ENOENT (No such file or directory)
access("/tmp", F_OK)                    = 0
mkdir("/tmp/437a94b0", 0700)            = 0
stat64("/tmp/437a94b0/4f5bba7d.tmp", 0xbf84bfc4) = -1 ENOENT (No such
file or directory)
lstat64("/tmp/437a94b0/4f5bba7d.tmp", 0xbf84bfc4) = -1 ENOENT (No such
file or directory)
access("/tmp/437a94b0", F_OK)           = 0
stat64("/tmp/437a94b0", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0
lstat64("/tmp/437a94b0", {st_mode=S_IFDIR|0700, st_size=4096, ...}) = 0
stat64("/tmp/437a94b0/4f5bba7d.tmp", 0xbf84bfb0) = -1 ENOENT (No such
file or directory)
lstat64("/tmp/437a94b0/4f5bba7d.tmp", 0xbf84bfb0) = -1 ENOENT (No such
file or directory)
access("/tmp/437a94b0", F_OK)           = 0
open("/tmp/437a94b0/4f5bba7d.tmp", O_RDWR|O_CREAT|O_EXCL|O_LARGEFILE, 0644) = 16
...

but the strace from running the failed code never does anything with
/tmp after the access() sycall.

The code that does the CompileAssemblyFromSourceBatch() is in a .dll
that mtest.exe loads.

What am I missing in the init of mono that prevents it from compiling
source on the fly? Everything else that I've tried with embedded mono
seems to work OK.

Cheers,
Carl
