I'm very interested in being able to have a native C++ executable which makes use of boost's TSS and also be able to wrap .NET modules with C++/CLI (i.e. /clr). And I much prefer it to be statically linked. The C++/CLI wrappers work fine when they are dynamically linked, but they cause a runtime initialization error (0xc000007b) whenever they are connected in only static links. It doesn't matter whether the host executable is compiled with /clr or not - somehow the MSVC linker knows to add some CLR initialization voodoo to the PE header whenever a static link to a /clr-enabled object is made. And that PE header voodoo seems to be incompatible with some of boost::thread's own brand of PE header voodoo which appears to be intended to provide TLS support for Windows. But as far as I can tell, I was able to get TLS working with MSVC9 even after commenting out the on_tls_prepare lines in tss_pe.cpp - commenting out the other lines wasn't necessary:
#if (_MSC_VER >= 1400) //#pragma section(".CRT$XIU",long,read) #pragma section(".CRT$XCU",long,read) #pragma section(".CRT$XTU",long,read) #pragma section(".CRT$XLC",long,read) static __declspec(allocate(".CRT$XLC")) _TLSCB __xl_ca=on_tls_callback; // static __declspec(allocate(".CRT$XIU"))_PVFV p_tls_prepare = on_tls_prepare; static __declspec(allocate(".CRT$XCU"))_PVFV p_process_init = on_process_init; static __declspec(allocate(".CRT$XTU"))_PVFV p_process_term = on_process_term; #else
I put together a test case that I'm pretty sure shows that TLS still works without that function. At the very least, can there be some preprocessor define to manually disable it for CLR compatibility? Or perhaps there is a way to adjust this voodoo to be compatible with the CLR initialization? I'm hosting the test case at: http://fenchurch.mc.vanderbilt.edu/files/TLS_CLR_Test.7z It includes a main function which runs a test of the TSS semantics, and a CLR class which tests console output via C++/CLI. I included binaries and the boost_thread.lib files for both the broken and "fixed" versions of tss_pe.cpp. Thanks, Matt Chambers
