Major step forward: 'tdragon' on SourceForge replied to my bug report about the installation failure.
The tdm4.5.2 installer has a check box on the first screen labeled "Check for updated files on the TDM-GCC server" that is checked by default. I don't know about folks in the gcc world, but to ME there's a difference between "updated files" and "new releases"... apparently, what the installer really means to be saying is, "If you leave this box checked, then I will silently use the highest-numbered release there is, regardless of which version of the installer you're now running." Hence, my ending up with 4.6.1 installed when I
thought I was installing 4.5.2.
So the installation error on the 32-bit version was actually an error attempting to grab a file for the 4.6.1 release (an error which doesn't seem to happen if you just run the 4.6.1 installer in the first place.) And the "experimental" version was 4.6.1 only, but I didn't know the 4.5.2 installer was doing the automatic swticheroo to that version.
If I uncheck the "check for updated files" checkbox, then I'm not offered the option of the experimental 32/64-bit version; there's only the one (32-bit) version, and it installs without error. Which leads me to wonder why you refer to the 32/64-bit version in your README file, since that only seems to be applicable to 4.6.1, and 4.6.1 isn't supposed to be just::thread-compatible? But I digress, as I now have a 32-bit 4.5.2 installed that does link with just::thread...but only if I use the explicit path name for the .a file (-ljustthread still fails to link).
Wow.
OK, next issue (lol). Consider the the following trivial program:
#include <iostream>
#include <thread>
using namespace std;
void hello()
{
cout << "Hello from hello (in thread?)\n";
}
int main()
{
thread t0(hello);
cout << "Hello from main!\n";
t0.join();
}
It builds clean under both VC9 and (now, finally) TDM4.5.2.
It runs fine under VC9, but under TDM4.5.2 I get the following "bonus" output after the expected two lines:
terminate called after throwing an instance of 'std::system_error'
what():
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.What's that about?
Thanks!
