similar to: [LLVMdev] Fails to compile w/ MinGW: sys/mman.h: No such file or directory

I am having trouble getting LLVM/Clang to compile from SVN/trunk on win32 using MinGW (4.7.1). The error is: sys/mman.h: No such file or directory ...and it happens during compilation of: [LLVM/Clang]\projects\compiler-rt\lib\enable_execute_stack.c I configured everything carefully as "CMAKE_BUILD_TYPE" "Release". I have in the PATH (in that order): - CMake - MinGW - Python

Is there interest in building/using compiler-rt on Windows? If there is none, probably we should just disable building it in CMake rules.

None. We're working on Windows port for ASan, but we don't use CMake to build it anyway.

Linux commit 746c9398f5ac ("arch: move common mmap flags to linux/mman.h") moved a few mmap flags, particularly MAP_PRIVATE, from asm/mman.h to linux/mman.h. This broke klibc's build, which uses MAP_PRIVATE. linux/mman.h includes asm/mman.h, so this commit merely includes linux/mman.h instead of asm/mman.h.

Hi, I tried to do a build with CMake, Ninja, and MinGW32 and MinG64 respectively: MinGW32 failed on an missing sys/mman.h (POSIX-specific header): D:/test/llvm-trunk/projects/compiler-rt/lib/enable_execute_stack.c:13:22: fatal error: sys/mman.h: No such file or directory #include <sys/mman.h> ^ MinGW64 failed on an #error directive:

I'm posting this here to document what I encountered and the solution I found, in hopes that others may find it useful. When building clang 3.2 on Linux (Ubuntu 12.04, 32-bit, x86 PC), I received the following errors (messages from the make output): ... make[4]: Entering directory `/home/youngmj/DevTools/LLVM/Version_3.2/build/tools/clang/runtime/compiler-rt' /bin/sh: 1:

klibc fails to compile on sparc64 since the kbuild switch: In file included from include/sys/mman.h:11, from klibc/malloc.c:8: linux/include/asm/page.h:18:2: error: #error No page size specified in kernel configuration the current dirty build hack is to define CONFIG_SPARC64_PAGE_SIZE_8KB in the sparc64 MCONFIG. belows patch removes the asm/page.h include. another way to fix

Hi Michael, you don't need compiler-rt to use clang. If you don't need it, I suggest you don't bother building it. Ciao, Duncan.

Dear Alexey, Yes I am sure that the llvm, clang and compiler-rt are synced to the same version. I downloaded them all from git http://llvm.org/docs/GettingStarted.html#git-mirror I think I need compiler-rt for my project but I'll verify it again to see if I can proceed without it. You are correct that compiler-rt is compiled with the just built clang. The complete command that gives an error

Hi, I am trying to build llvm along with clang and compiler-rt. When I run make, I am getting the following compilation error (I tried compiling llvm-3.2, which is what I need for my project, but also tried llvm-3.3 and the current llvm source from the git repository). ... COMPILE: clang_linux/full-x86_64/x86_64:

yes I think that is correct. I wrote a simple program to print if sizeof(uintptr_t) != sizeof(unsigned char *) and when I compile with gcc -m64 and execute it on a 64-bit host (that is different from the 32-bit laptop on which I originally compiled the program), it says the sizes are not equal.

You can disable -Werror by adding the cmake flag -DLLVM_ENABLE_WERROR=OFF, which should let it just ignore that (that's also the default, so you must have turned it on somewhere) On Jul 31, 2013, at 13:09 , Pranav Garg <pranav.garg2107 at gmail.com> wrote: > Hi, > > I am trying to build llvm along with clang and compiler-rt.
