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

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:

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.
I am new to compiling.
I am trying to compile iperf3 for Windows 10 because there is no official Windows distribution of iperf3 and for the learning experience. I am trying to do so on the new Windows Subsystem for Linux feature via Bash on Ubuntu on Windows, also for the learning experience.
I installed mingw-w64, which should give me the proper compiler and environment necessary for cross-compiling:
sudo apt-get install mingw-w64
This put two directories into my /usr directory:
i686-w64-mingw32
x86_64-w64-mingw32
It also put a bunch of things that look like compilers into /usr/bin.
I unzipped the .tar.gz file from iperf3 and navigated into it. Then, I run ./configure --host=i686-w64-mingw32.static and it completes without errors.
I note that the output of the command has a worrisome line: checking for i686-w64-mingw32.static-gcc... no
I note that the Makefile's CC variable is set to gcc, which doesn't sound like the proper compiler.
Then, I run make. It fails with errors:
collect2: error: ld returned 1 exit status
make[2]: *** [iperf3] Error 1
make[2]: Leaving directory `/home/snip/iperf3/iperf-3.1.4/src'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/snip/iperf3/iperf-3.1.4/src'
make: *** [all-recursive] Error 1
I also see the line: libtool: warning: undefined symbols not allowed in i686-w64-mingw32.static shared libraries; building static only
I think that the ./configure is not working correctly since it appears to have not found the right compiler for my --host argument and put it in the Makefile.
What am I doing wrong?
EDIT:
I changed the command to ./configure --host=i686-w64-mingw32 per comments and it completes without error. But no makefile is created so make yields make: *** No targets specified and no makefile found. Stop.
What am I doing wrong, now?
EDIT 2:
Looks like the ./configure actually is failing. Last line of its output is nanosleep() required for timing operations., which seems to mean that its missing a library for nanosleep.
How do I get nanosleep?
mingw doesn't support nanosleep. So programs using it cannot be compiled using mingw-w64.
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!
I'm trying to test this script from oracle to get active NFS clients on Ubuntu 10.04, but I can' get it to run.
To achieve that, I first installed dtrace following these instructions. This is what I've done exactly:
apt-get install bison flex zlib1g-dev libelf-dev binutils-dev libdw-dev libc6-dev-i386
wget ftp://crisp.dyndns-server.com/pub/release/website/dtrace/dtrace-20121009.tar.bz2
tar xfj dtrace-20121009.tar.bz2
cd dtrace-20121009
make all
make install
make load
However, I get this warning when compiling:
=================================================================
=== You need /usr/lib/libdwarf.a and /usr/lib/libbfd.a installed to build.

NOTE: The build is complete, but build/ctfconvert is not available.
This means you will get run time errors from the io.d and sched.d files
due to undefined kernel structure definitions. Simply delete or rename
these files until a fix can be put in place to handle older
distros which do not have the required libdwarf dependencies.
(Typical error is references to undefined struct definitions such
as dtrace_cpu_t).

I've installed libdw-dev and binutils-dev, but taking a look at the makefile, it seems it looks for libdwarf.so, and libdw on my system is named libdw.so.
To circunvent this, I create a symlink with ln -s /usr/lib/libdw.so /usr/lib/libdwarf.so. After doing so, compiling fails.
cd cmd/ctfconvert ; make --no-print-directory
gcc -g -I. -I../../ -I../../libctf -I../../common -I../../uts/common -I../../linux -I/usr/include/libdwarf -c dwarf.c

So, let's undo that. I remove the symlink, compile again, run make install and make load and hope everything is fine. And everything seems to be fine.
But, then I try to run the script mentioned above, and it fails:
# ./get_ngs_clients.d
dtrace: failed to compile script ./get_ngs_clients.d: Preprocessor not found
I have no clue on what's going on. I have gcc installed, just in case.

If you do not have libdwarf.a on your system, the ctfconvert tool will not build. (libdwarf.a and libdw.a are not the same).
If ctfconvert does not build, then any of your own, or the dtrace etc/*.d scripts may not load. (Dtrace force loads these scripts for you automatically, which is annoying). Any script which relies on structure definitions will then fail.
As of May 2013, I am looking at seeing what it takes to update to libdw.a since this seems to be the modern replacement for libdwarf.
(posted by the 'author' of DTrace/Linux).
Have you tried to add --enable-dtrace=false to /.configure?
Or maybe --with-dtrace=false?
That should do the trick I think...
I installed SFML from scratch today so I could work on a game. I downloaded the source, ran sudo make install, tried compiling one of my old projects, and I couldn't get it to link properly. So I tried running a simpler project: one of the samples in the tutorials. I tried to compile this one specifically, but I get these errors:
g++ -o atest test.cpp -lsfml-graphics -lsfml-window -lsfml-system /tmp/ccaa86fR.o: In function `main':
test.cpp:(.text+0x1d2): undefined reference to `gluPerspective'
collect2: ld returned 1 exit status
make: *** [test] Error 1
Trying an even simpler project, the one in the initial tutorial, I don't run into problems compiling. However, when I try to run it, I get this error:
./atest: error while loading shared libraries: libsfml-graphics.so.1.6: cannot open shared object file: No such file or directory
I checked, and the files did install to /usr/local/lib/ which is where they're supposed to go as far as I know. What am I doing wrong here?
-lGLU should fix the first error and for the second one make sure /usr/local/lib/ is in your ldconfig search path (/etc/ld.so.conf and /etc/ld.so.conf.d/* under Ubuntu) and that you ran ldconfig: sudo ldconfig -v then try running again.
