I was trying to go ahead and get Derelict working on Tiger, and ran into this curious habit of build. Apparently, this claim:
| Quote: |
For the DigitalMars compiler, this also specifies the top-level location where object files are created. By default, object files are created in the same directory as the corresponding source file.
|
Doesn't hold true for the GDC version of build. Indeed, whenever I try to specify the -od switch at all, it recognizes it as the -o outfile switch. What's happening is that in the GDC version of build, all the *.o files are being created in the directory where build was invoked, but then when build goes to link, it assumes that the object files are in the same folder as the corresponding *.d files.
I whipped up a quick test to verify:
./main.d
./test/test.d
main.d:
| Code: |
import test.test;
int main(char[][] args)
{
doSomething();
return 0;
}
|
test/test.d:
| Code: |
module test.test;
import std.file;
void doSomething()
{
printf("Test.\n");
}
|
Building the code using a straight call to GDC works fine:
| Code: |
? gdc -o main main.d test/test.d
|
However, using build yields the following message:
| Code: |
? build -Xstd main.d
gdc: test/test.o: No such file or directory
|
What I was thinking, is patching build to invoke the gdmd wrapper script on Posix systems. GDMD supports the -od argument. I don't know how feasible this is.

Currently, Build invokes 'gdc'. I'd be interested in knowing what the exact command line generated by Build looked like. You can see this by using the '-V' switch.
But in the meantime, the patch is easy. There is one line of code to change.
char[] vCompiler = "gdc";
becomes
char[] vCompiler = "gdmd";
Let me know how it goes so I can improve Build.

I remember trying that, and it worked if you specified -od, but not if you didn't.
Here's the -V output from a clean SVN build of er... build:

I applied the following patch and got it working, although I'm not 100? positive of the repercussions (I can't think of any):
