Hi,
I installed the cfrontend 1.5 and LLVM 1.5 from source in cygwin
successfully using GCC3.4.3 and binutils2.15 (as in makefiles do not
complain errors except some warnings).
However when I do this, there are some errors like,
***************************************************************
u0201201 at 9nnvf2ay /home/cfrontend/install/lib
$ llvm-ranlib libiberty.a
llvm-ranlib: Error opening archive file: libiberty.a
****************************************************************
This happens to llvm-ranlib libiberty.a, llvm-ranlib libstdc++.a,
llvm-ranlib libsupc++.a too. May I know what is the cause and how to
solve it? (I saw a post similar to this, but there is no solution
provided.)
Another problem is when I run hello.c which is
#include <stdio.h>
int main() {
printf("hello world\n");
return 0;
}
I got this,
*******************************************************
u0201201 at 9nnvf2ay /home
$ llvm-gcc hello.c -o hello
gccld: warning: Cannot find library 'user32'
gccld: warning: Cannot find library 'kernel32'
gccld: warning: Cannot find library 'advapi32'
gccld: warning: Cannot find library 'shell32'
********************************************************
The lli tool doesn't work as well.
However, llvm-dis,llc,gcc hello.s -o hello.native,./hello.native work.
(I have not try with the other tools yet)
Your help will be very much appreciated.
Regards,
Kiat

This isn't a problem, it only makes things slower not incorrect. Unfortunately I have lost my Cygwin machine (disk failure) so I can't diagnose this for you. If you want to take a stab at debugging llvm-ranlib and discovering why it is failing to open the file, that would be a great help to us. The error message is coming from a sys::Path method when it tries to open libiberty.a. Chances are its a path construction problem involving a space on Windows. Try installing llvm-ranlib into a path that doesn't have a space in it?> Another problem is when I run hello.c which is > #include <stdio.h> > int main() { > printf("hello world\n"); > return 0; > } > > I got this, > ******************************************************* > u0201201 at 9nnvf2ay /home > $ llvm-gcc hello.c -o hello > gccld: warning: Cannot find library 'user32' > gccld: warning: Cannot find library 'kernel32' > gccld: warning: Cannot find library 'advapi32' > gccld: warning: Cannot find library 'shell32' > > ********************************************************This isn't a big deal. Its just the llvm-gcc linker warning you that its default search path couldn't find the required libraries to link with. This doesn't affect the generated bytecode file.> The lli tool doesn't work as well.LLI is known not to work on Cygwin.

Unfortunately we simply don't have the resources to address Cygwin ports at this time. If you find any solutions to the above problems, please let us know and we'll gladly accept patches against it.> > Your help will be very much appreciated.> Regards, > Kiat >Thanks for trying LLVM on Cygwin and letting us know your experience.

I believe you can use the other llvm tools to get a hello world assembled and linked, using ld. Have not tried it yet though. Aaron
Hi, I am wondering whether the bytecode generated by my llvm-gcc is correct? When I run $ llvm-gcc hello.c -o hello What I get is hello.exe.bc, and hello.exe (I can actually llvm-dis the bytecode file which is hello.exe.bc). However, I do not get a shell script(named hello) as stated in the documentation...

Hi, Maybe I can provide you with the installation steps that I done in my machine. What I did is, 1. first install cygwin, I attached a list of the packages I installed. (there are quite a lot of packages) 2. build the binutils-2.15. 3. Then gcc-3.4.3. (I am using the new binutils which is the 2.15) 4. Next, I follow the instructions in the LLVM documentation to further build the cfrontend then LLVM. Hope that it helps.
