'stdlib.h' file not found or lld cannot open crt1.o/crti.o/crtn.o: no such file or directory #55592

Closed House-Men closed 11 months ago

My host env = Windows10(x64) + CMake3.23.1 + Ninja1.11.0 + Clang14.0.3 clang version 14.0.3 Target: x86_64-pc-windows-msvc Thread model: posix InstalledDir: D:\Program Files\LLVM\bin

Target host pack = gcc-arm-8.2-2018.08-x86_64-arm-linux-gnueabihf

During compilation issue 1:

include_next <stdlib.h> can't find error

Reason is clang auto search add -isystem Header file order error

include_directories(
    SYSTEM
    ${CMAKE_SYSROOT}/arm-linux-gnueabihf/include/c++/8.2.1
    ${CMAKE_SYSROOT}/arm-linux-gnueabihf/include/c++/8.2.1/arm-linux-gnueabihf
    ${CMAKE_SYSROOT}/arm-linux-gnueabihf/include/c++/8.2.1/backward
    ${CMAKE_SYSROOT}/lib/gcc/arm-linux-gnueabihf/8.2.1/include
    ${CMAKE_SYSROOT}/lib/gcc/arm-linux-gnueabihf/8.2.1/include-fixed
    ${CMAKE_SYSROOT}/arm-linux-gnueabihf/include
    ${CMAKE_SYSROOT}/arm-linux-gnueabihf/libc/usr/include
    )

By Manual setting resolved It is not clear whether the automatic addition of -isystem can be ignored ? Later I learned that it can be -nostdinc shielded.

issue 2:

ld.lld: error: cannot open crt1.o/crti.o/crtn.o: no such file or directory
cmake set link_directories(${CMAKE_SYSROOT}/arm-linux-gnueabihf/libc/usr/lib) can't solve
cmake set target_link_libraries(demo ${CMAKE_SYSROOT}/arm-linux-gnueabihf/libc/usr/lib/crt1.o ...) can't solve

Unable to find a solution, I had no choice but to find another way

mklink %SYSROOT%/arm-linux-gnueabihf/libc/usr/lib/crt1.o %SYSROOT%/arm-linux-gnueabihf/lib
mklink %SYSROOT%/arm-linux-gnueabihf/libc/usr/lib/crti.o  %SYSROOT%/arm-linux-gnueabihf/lib
mklink %SYSROOT%/arm-linux-gnueabihf/libc/usr/lib/crtn.o %SYSROOT%/arm-linux-gnueabihf/lib

The automatic search is successful only when the position is changed finally Is there no way to set this path ? After cmake is manually set, multiple duplicates of - l param are automatically added. There is no way to ignore the automatically added - L param ? After comparing arm-linux-gnueabi-g++ -v , I try

set(CMAKE_SYSROOT E:/packages/arm-linux-gnueabihf-8.2/arm-linux-gnueabihf/libc)
add_link_options(--gcc-toolchain=${CMAKE_SYSROOT}/../..)

After setting, the automatic search of Inc and lib by clang is normal. But I haven't found how to manually set clang to search the crtlib directory, maybe only by setting -nostdlib to make -l path/crtx.o take effect.

@House-Men Do you still experience this with Clang 17 or trunk?

My host env = Windows10(x64) + CMake3.23.1 + Ninja1.11.0 + Clang14.0.3 clang version 14.0.3 Target: x86_64-pc-windows-msvc Thread model: posix InstalledDir: D:\Program Files\LLVM\bin Target host pack = gcc-arm-8.2-2018.08-x86_64-arm-linux-gnueabihf During compilation issue 1: ```console include_next <stdlib.h> can't find error ``` Reason is clang auto search add `-isystem` Header file order error ```cmake include_directories( SYSTEM ${CMAKE_SYSROOT}/arm-linux-gnueabihf/include/c++/8.2.1 ${CMAKE_SYSROOT}/arm-linux-gnueabihf/include/c++/8.2.1/arm-linux-gnueabihf ${CMAKE_SYSROOT}/arm-linux-gnueabihf/include/c++/8.2.1/backward ${CMAKE_SYSROOT}/lib/gcc/arm-linux-gnueabihf/8.2.1/include ${CMAKE_SYSROOT}/lib/gcc/arm-linux-gnueabihf/8.2.1/include-fixed ${CMAKE_SYSROOT}/arm-linux-gnueabihf/include ${CMAKE_SYSROOT}/arm-linux-gnueabihf/libc/usr/include ) ``` By Manual setting resolved It is not clear whether the automatic addition of `-isystem` can be ignored ? Later I learned that it can be -nostdinc shielded. issue 2: ```console ld.lld: error: cannot open crt1.o/crti.o/crtn.o: no such file or directory cmake set link_directories(${CMAKE_SYSROOT}/arm-linux-gnueabihf/libc/usr/lib) can't solve cmake set target_link_libraries(demo ${CMAKE_SYSROOT}/arm-linux-gnueabihf/libc/usr/lib/crt1.o ...) can't solve ``` Unable to find a solution, I had no choice but to find another way ```ps mklink %SYSROOT%/arm-linux-gnueabihf/libc/usr/lib/crt1.o %SYSROOT%/arm-linux-gnueabihf/lib mklink %SYSROOT%/arm-linux-gnueabihf/libc/usr/lib/crti.o %SYSROOT%/arm-linux-gnueabihf/lib mklink %SYSROOT%/arm-linux-gnueabihf/libc/usr/lib/crtn.o %SYSROOT%/arm-linux-gnueabihf/lib ``` The automatic search is successful only when the position is changed finally Is there no way to set this path ? After cmake is manually set, multiple duplicates of - l param are automatically added. There is no way to ignore the automatically added - L param ? After comparing arm-linux-gnueabi-g++ -v , I try ```cmake set(CMAKE_SYSROOT E:/packages/arm-linux-gnueabihf-8.2/arm-linux-gnueabihf/libc) add_link_options(--gcc-toolchain=${CMAKE_SYSROOT}/../..) ``` After setting, the automatic search of Inc and lib by clang is normal. But I haven't found how to manually set clang to search the crtlib directory, maybe only by setting -nostdlib to make -l path/crtx.o take effect.
