i want to build Clang,and i do follow the steps in the install.txt in the clang source directory but when i run 'make' in the Clang source directory ,it stops at "Linking Debug executable clang-cc",and i tried many times ,but it did not work,it just stopped there. how can i do? PS: my os is Ubuntu and the picture is in the attachment . and i waited for an hour,but it still

Hi, Ive been trying to build llvm/clang from source, but at the point where the make reaches ' llvm[4]: Linking Debug+Asserts executable clang', it seems that the make just seems to freeze or become unresponsive. When it reaches this point, almost no CPU/IO activity seems to take place, and yet the 'make' does not seem to progress any further either. Ive been waiting/watching at

I'm trying to customize llvm by adding a header file of my own and tweaking things accordingly. While building, things go well until a certain point where it stops seeing the includes of my file. I'm working on Ubuntu 12.04 with llvm-3.1 on a custom target (mips-like), gcc-4.6 and clang-3.2 (i've tried 3.1 too). >From what i've understood, when it builds the first binaries of

Hello Mr. Ciao and people on our list I tried this last night and now in the morning I captured the problem status. Could you please advise me on this problem? - I downloaded brand new clang+llvm and compiled it as instructed from the url below. >> http://clang.llvm.org/get_started.html - I added some code to tools/clang/tools/driver/driver.cpp 343 int main(int argc_, const char **argv_)

Hi, > Yes, they both are exactly the same. then I don't know what is going on. I suggest you send a copy of comb.ll to the list so that we can see for ourselves.

Hello I need some help here please. If we compile source files directly in to native code: $ clang -O3 -lm *.c then the runtime is like following real 0m2.807s user 0m2.784s sys 0m0.012s and If we emit LLVM bytcode and apply optimizations $ clang -O3 -c -emit-llvm *.c $ llvm-link *.o -o comb.ll $ time lli ./comb.ll then the runtime is real 0m2.671s user 0m2.640s sys 0m0.020s But, if I

Thanks Duncan It was really helpful.

Hello list I have questions about compiling Clang+llvm. I compile as the link below instructs. http://clang.llvm.org/get_started.html I do on Ubuntu 12.04. `time make -j5` prints for about 13 minutes to compile a brand new version of Clang+llvm. And after this I edit some C++ code(clang/tools/driver/driver.cpp) and compiles using the very same makefile which was used above sentence. But this

Hello, I have trouble compiling programs using clang on Ubuntu-Natty (getting some linker errors). So I generated a object file using "-c" and then used gcc to generate the final executable. It worked fine. I tried the following method also: $ clang -O0 -c -flto foo.c $ llc foo.o $ gcc foo.o.s It also worked. However the problem is I am getting different runtimes using the two

Hello Duncan I tried your method and it works fine. What would be the next step to produce the final executable? I have tried the following but it is producing an error $ gcc -fplugin=/path/to/dragonegg.so -S *.c -fplugin-arg-dragonegg-emit-ir | opt -adce $ clang *.s Regards Shahzad On Fri, Jun 8, 2012 at 9:10 AM, Duncan Sands <baldrick at free.fr> wrote: > Hi Shahzad, > >

Duncan, Many thanks for your comments. The core issue we're running into is this: $ GCC=/usr/bin/gcc LLVM_CONFIG=/usr/bin/llvm-config make Compiling utils/TargetInfo.cpp Linking TargetInfo ld: fatal: library -lLLVMSupport: not found ld: fatal: file processing errors. No output written to TargetInfo collect2: error: ld returned 1 exit statusAll other gyrations are attempts to shoehorn

Hello Duncan Sorry for the mistake. Actually that error occurred when I was compiling all the files at once, NOT in for loop. The for loop is working perfectly as it is dealing with individual files. I have now one new issue. Let me specify it briefly. If I compile the program using the following command line i.e. $ clang -O3 -lm *.c then $ time ./a.out real 0m2.606s user 0m2.584s sys

Thanks for the answer, So if i understand right, i can't directly compile the c code using clang. And i need to manually generate some llvm ir to replace the builtin function.
