error compiling uClibc (__NR_or1k_atomic undeclared) - gcc

I am following http://openrisc.net/toolchain-build.html to build gcc toolchain for openrisc or32.
I'm doing 'building by hand' flow and had passed
binutils
stage 1 gcc
install linux headers
and was to do 'compile uClibc' which is composed of commands below.
$ git clone git://openrisc.net/jonas/uClibc
$ cd uClibc
$ make ARCH=or32 defconfig
$ make PREFIX=${SYSROOT}
$ make PREFIX=${SYSROOT} install <br>
when I run 'make ARCH=or32 defconfig', I get this error.

Has anybody had same problem? I use CentOS 6.4.

gcc searches for the header file from the system in the order
/usr/local/include
libdir/gcc/target/version/include (libdir was /usr/lib in my case)
/usr/target/include
/usr/include
my system had sys/syscall.h under /usr/include so that file was used when sys/syscall under uClib/include should have been used. So I added -nostdinc so that gcc doesn't search the standard include path. Now it became
make PREFIX=${SYSROOT} -nostdinc
and it works!
The following command was also modified
make PREFIX=${SYSROOT} -nostdinc install
Cheers!

gcc/gfortran 11 cannot find headers/libraries in default locations

After upgrading python 3.8.6 to 3.9.10 using homebrew, my Cython extensions no longer without explicitly adding /usr/local/include (for my Intel MacBook) or /opt/homebrew/include to the include_dirs of my extension.

In the file above, I have hardcoded the location (temporarily) of the homebrew library dir and added some functionality for the include dir based on /opt/homebrew being found. If I remove this from the file, compilation fails as eccodes.mod cannot be found, see the output when I run the command generate by python/CMake manually:

This extension is part of a larger project that is build using CMake. When running the gfortran command manually, the same errors indicating that eccodes.mod cannot be found. The file is however located on a default location on the gfortran/gcc search path:
locate eccodes.mod
/opt/homebrew/Cellar/eccodes/2.24.2/include/eccodes.mod
/opt/homebrew/include/eccodes.mod
And the search path for gfortran:
gfortran -E -Wp,-v -
#include <...> search starts here:
/opt/homebrew/include
/opt/homebrew/Cellar/gcc/11.2.0_3/bin/../lib/gcc/11/gcc/aarch64-apple-darwin21/11/include
/opt/homebrew/Cellar/gcc/11.2.0_3/bin/../lib/gcc/11/gcc/aarch64-apple-darwin21/11/include-fixed
/Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk/usr/include
/Library/Developer/CommandLineTools/SDKs/MacOSX12.sdk/System/Library/Frameworks
End of search list.
Another project uses gcc/ld and has a similar problem. I need to explicitly add LINK_DIRECTORIES(/opt/homebrew/lib) to CMakeList.txt in order for gcc to find the eccodes library. Without that, I get:
gcc-11: warning: this compiler does not support X86 (arch flags ignored)
ld: library not found for -leccodes
collect2: error: ld returned 1 exit status
make[2]: *** [src/smoothModeS-v51/smoothModeS-v51.x] Error 1
make[1]: *** [src/smoothModeS-v51/CMakeFiles/smoothModeS-v51.x.dir/all] Error 2
make: *** [all] Error 2
Adding the paths to CPATH and LIBRARY_PATH had no effect.
This method works but seems hard to maintain. What am I missing and what has changed that gfortran/gcc no longer search in the default paths for but libraries and headers/modules?
EDIT
Just found that the standalone executable that uses similar code as the python extension and also uses eccodes has a similar issue. If I do not include INCLUDE_DIRECTORIES(/opt/homebrew/include) in CMakeLists.txt , I get:
cd <project_dir>/buildDebug/src/collocEHS && /opt/homebrew/bin/gfortran -I<project_dir>/buildDebug -I<project_dir>/include -I<project_dir>/src/readASTERIX2 -I<project_dir>/src/geomag70_linux -I<project_dir>/src/libDTG -fallow-argument-mismatch -ffpe-trap=invalid,zero,overflow -DPREC32 -DLINUX -DIS_LITTLE_ENDIAN -DUSEWALLTIME -DHAS_BLAS -DHAS_LAPACK -DGRIB32 -DTIMING -ffixed-line-length-none -g -fcheck=all -Wall -fcheck=bounds -O0 -g -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.1.sdk -c <project_dir>/src/pynwp/readAtmosphereGen.f90 -o CMakeFiles/collocEHSv2.dir/__/pynwp/readAtmosphereGen.f90.o

make: *** [all] Error 2
So I guess the problem is unrelated to python but more with gcc/gfortran (gcc version 11.2.0 (Homebrew GCC 11.2.0_3).
EDIT 2
A reboot of the laptop fixed the issue with the python extension build and setup.py requiring additional directories. For normal builds using CMake, I still require the extra INCLUDE_DIRECTORIES and LINK_DIRECTORIES order for gcc/gfortran to find libraries installed by brew in /opt/homebrew (or /usr/local for intel MacBook).
As per homebrew devs, this is desired behaviour: /opt/homebrew and /usr/local are "special" directories to be manually added in e.g., CMake projects. This is explained in my bug report on home-brew's GitHub, see https://github.com/Homebrew/homebrew-core/issues/95561.
I haven't been able to confirm this with documentation.

How to link jemalloc shared library using cmake

I'm trying to link the jemalloc library into my application at build time using it as a generic implementation. According to https://github.com/jemalloc/jemalloc/wiki/Getting-Started the linking flags to use are:
-L`jemalloc-config --libdir` -Wl,-rpath,`jemalloc-config --libdir` -ljemalloc `jemalloc-config --libs`
So I did the following CMakeLists.txt:
cmake_minimum_required(VERSION 2.8.12.2)
project(widget)
include_directories(include)
file(GLOB SOURCES "src/*.cpp")
add_executable(widget ${SOURCES})
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -L`jemalloc-config --libdir` -Wl,-rpath,`jemalloc-config --libdir` -ljemalloc `jemalloc-config --libs`")
But when I do make I get the following errors:
Linking CXX executable widget
c++: error: `jemalloc-config: No such file or directory
c++: error: unrecognized command line option ‘--libdir`’
c++: error: unrecognized command line option ‘--libdir`’
c++: error: unrecognized command line option ‘--libs`’
make[2]: *** [widget] Error 1
make[1]: *** [CMakeFiles/widget.dir/all] Error 2
For future generations, as this still comes up as one of the first links on Google.
Jemalloc comes with pkg-config setup, which can be used like this:
find_package(PkgConfig REQUIRED)
pkg_check_modules (JEMALLOC jemalloc)
pkg_search_module(JEMALLOC REQUIRED jemalloc)
include_directories(${JEMALLOC_INCLUDE_DIRS})
target_link_libraries(your_target_name ${JEMALLOC_LIBRARIES})
execute_process() command is your friend. Use it to run jemalloc-config executable and then put its output into CMake variables.
find you root_dir of jemalloc. Mine is /Users/lion/homebrew/Cellar/jemalloc/5.2.1_1/lib/
(I install jemalloc by brew on macOS)
link (soft link) all its lib to your local lib ln -s /Users/lion/homebrew/Cellar/jemalloc/5.2.1_1/lib/* /usr/local/lib
Then it works!

Compiling superopt on windows

I'm triing to compile the superoptimizer on windows. (https://github.com/bonzini/superopt)
Unfortunatly my knowledge of make is very limited. I tried:
make CPU=-D386 superopt
Which gives me the error:
cc superopt.c -o superopt
process_begin: CreateProcess(NULL, cc superopt.c -o superopt, ...) failed.
make (e=2): The system cannot find the file specified.
make: *** [superopt] Fehler 2
After setting the compiler to gcc manually with:
make CPU=-D386 superopt CC=gcc
I get the following error:
gcc superopt.c -o superopt
In file included from superopt.c:27:0:
superopt.h:104:2: error: #error You have to choose target CPU type (--with-arch).
#error You have to choose target CPU type (--with-arch).
^
In file included from superopt.h:130:0,
from superopt.c:27:

extern const UQItype __clz_tab[];
^
superopt.c:32:21: fatal error: version.h: No such file or directory
compilation terminated.
make: *** [superopt] Fehler 1
It seems it does't properly selects i386.
Any hints would be greatly appreciated.
That is not the source code of
GNU superopt. It is the source code of someone's project
to patch GNU superopt, last updated 2008, and seemingly
abandoned a hard-hat area.
This is the source code of
GNU superopt. Extract the tarball and build as you have attempted
with:
make CC=gcc CPU=-DI386 superopt
Note: I386, not 386.
You will see warnings like:
warning: incompatible implicit declaration of built-in function 'foo'
because the 20 yearold C code does not diligently include the standard
headers that prototype the standard functions that it calls, but superopt will build successfully.

Install nullfs on Debian

I am using a java program. It automatically creates log files in a directory, but I am doing that myself a different way with tee. I cannot find an easy way to disable the logs, so I am resorting to using nullfs.
I cloned it with
git clone https://github.com/xrgtn/nullfs.git
and I ran
make nul1fs
as instructed. It terminates within a second, with the following output:
cc "-lfuse" nul1fs.c -o nul1fs
nul1fs.c:13:18: fatal error: fuse.h: No such file or directory
compilation terminated.
make: *** [nul1fs] Error 1
I tried apt-get source fuse and copying fuse.h into the nullfs directory, but nothing changed.
I have FUSE installed. I'm running Debian wheezy x86_64.
You need the development package of FUSE, which contains the fuse.h you're missing. Do a apt-get install libfuse-dev and it should work.
Copying the header file in the source directory did not work, because in nul1fs.c you'll notice that fuse.h is included with angle brackets. This means, the header file will be searched in the system-wide include paths. That usually means /usr/include.
Note that you then may run into this error:
$ make nul1fs
cc "-lfuse" nul1fs.c -o nul1fs
/tmp/ccbt0X7c.o: In function `main':
nul1fs.c:(.text+0x3c3): undefined reference to `fuse_main_real'
collect2: error: ld returned 1 exit status
make: *** [nul1fs] Error 1
It's a documented bug with a workaround: put the linker flags after the file lists. I.e. compile nul1fs with:
cc nul1fs.c -o nul1fs -lfuse
and not with make nul1fs, which boils down to
cc -lfuse nul1fs.c -o nul1fs

Trouble compiling FUSE filesystems on OS X

OS: OS X Mavericks (v10.9)
FUSE: OSXFUSE v2.6.2
I'm trying to compile the loopback filesystem in C, but I'm getting this error:
$ make
cc -D_FILE_OFFSET_BITS=64 -I/usr/local/include/osxfuse/fuse -Wall -g -F/Library/Frameworks -o loopback loopback.c -losxfuse
ld: library not found for -losxfuse
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [loopback] Error 1
Trying to compile boxfs2 also produces this error:
$ make

Perhaps you should add the directory containing `libxml-2.0.pc'
to the PKG_CONFIG_PATH environment variable

Compiling boxfs.c
cc -c boxfs.c -o boxfs.o
boxfs.c:15:10: fatal error: 'fuse.h' file not found
#include <fuse.h>
^
1 error generated.
make: *** [boxfs.o] Error 1
Can anyone point me in the right direction?
As far as the first problem, you need the OSXFUSE library somewhere the compiler can see it, or you need to tell the compiler where it is.
You may have some success using mdfind to locate the osxfuse library file, then add -L/path/to/osxfuse to the compile/configure script to the makefile.
Similarly, the for the second, try making sure boxfs2 knows about the fuse header: Looks like adding -I/usr/local/include/osxfuse/fuse might do it.
