I have a problem trying to compile a library. I am using curve25519-donna to generate key pairs. I have already downloaded the library and unzipped the file, but my problem is with the compilation.
I have changed my directory to curve25519-donna-1.3 and this is the code I tried to use the compile the library:
env CC='gcc -02' make
And this was the outcome.
Makefile:23 recipe for target 'curve25519-donna-c64.o' failed
make: *** [curve25519-donna-c64.o] Error 1
I am running on a Raspberry pi OS, am I missing some gcc's that I need to install in this operating system?
I've upgraded and updated but I am still having problems with this. Any help will be much appreciated, thanks!!

I'm working with a Linux driver that is building on v5.7.x kernels but not on the latest v5.8.x releases.
To summarise, most of the driver is pre-built and the kernel interface is built on the target. This involves a make -f Kbuild command.
Having checked all of the relevant kernel interface files for any changes that would affect us, normally the driver would just build as usual on a new kernel. However, this time we get the following error:
make[2]: *** [scripts/Makefile.modpost:111: /path/to/source/Module.symvers] Error 1
make[1]: *** [Makefile:1669: modules] Error 2
make[1]: Leaving directory '/usr/src/kernels/5.8.0-1.el8.elrepo.x86_64'
make: *** [Kbuild:26: default] Error 2
This is from CentOS 8.1, but the same error has been seen on Ubuntu 20.04.
I am no expert on this so interpreting these errors is a bit difficult. I have tried building with the KBUILD_VERBOSE flag and it doesn't really provide any useful information, other than the build succeeding until this point.
On previous kernels the Module.symvers file would be created but empty. On 5.8 this file is not created at all presumably due to this error. As a result, the .ko file is not created.
Finally, if we drop in the source files rather than the pre-built .o files the build does succeed. These .o files are built with a very old version of GCC (4.4.7) but we have also tried building with a much newer version (8.3.1), the same version as the target machine.
I would appreciate suggestions for things to check. Let me know if any other details would help.
Edit:
I ran make on Makefile.modpost manually and got the following output:
sudo make -f ./scripts/Makefile.modpost
WARNING: Symbol version dump "vmlinux.symvers" is missing.

make -f /scripts/Makefile.modfinal

I am answering my own question in case it helps anyone else with this problem. Although it has never been an issue in the past, we've always had a warning that the corresponding .o.cmd file was not present for our .o_shipped files. This appears to be important in kernel 5.8 onwards and my fix was to add a touch command to the Kbuild file (i.e. "touch .driver.o.cmd"). This does not remove the warning but it allows the driver to build as normal.
I have a problem by compiling a driver (WLAN-dongle Edimax ac600).
I´m using an Archlinux on my raspberry-pi and want to install my dongle for 5Ghz. During comiling the driver I get this message. I tried to install the linux-headers without success. (in other threads it will be a solution)
Here is my output of make:
[root#raspberry_pi_1 rtl8812AU]# make make ARCH=arm CROSS_COMPILE= -C
/lib/modules/4.9.43-1-ARCH/build M=/root/rtl8812AU modules make[1]:
*** /lib/modules/4.9.43-1-ARCH/build: No such file or directory. Stop. make: *** [Makefile:1576: modules] Error 2
I found out that my pi has a two-arch...-directories:
4.9.43-1-ARCH/
4.9.51-1-ARCH/
Only the second one has the build directory...
How can I fix the problem?!
thanks a lot,
a Linux noob...

Use uname -r to make sure which version of the kernel you use.
If it's 4.9.43 : you have newer version of the kernel and this confuse your installer. You should reboot on the 51 one
If it's 4.9.51 : You messed up your installation step and are trying to compile for an old target. You should review the compilation process and change every mention of the 4.9.43 to 4.9.51 since it's the version you use.
If you upgrade your kernel, you may have to rebuild the thing again (You may like to have script in the future ;) ) with the new kernel version.
I'm working on a Linux machine (debian) 64bit and created a simple project involving JNI. The program is running fine on Linux with the created Java project and the compiled .so file. The goal now is to compile the C++ part of the project into a .dll instead of a .so to get it to run on Windows machines.
I read some forums and some articles like this one Article, but all of those articles were about compiling from console and also didn't involve the necessary JNI includes.
I also downloaded the cross-compiler from the given article and tried to get it to run in Netbeans. Therefore I set up another C/C++ Tool Collection in Netbeans and told it to use the x86_64-w64-mingw32-gcc compiler for both C and C++. But Netbeans is giving me some errors compiling the file, telling me the x86_64-w64-mingw32-gcc compiler could not be found which is quite random I think because I selected it from the file chooser. Did any of you do something like this already, building a .ddl from Netbeans running on Linux? If yes, how did you get it to work?

#Edit: I'm a step further now: I installed the correct mingw32 tools: sudo apt-get install mingw32. The programm does now compile without errors using the i586-mingw32msvc-g++ compiler but it still results in a .so instead of a .dll. I guess it has something to do with the make command but I haven't found anything about that yet.
I have been trying to figure out how to compile a kernel module. I started with http://www.tldp.org/LDP/lkmpg/2.6/lkmpg.pdf to learn. I then found Compiling a kernel module, header problems, makefile problems to get my makefile going. After running make. I get the following output:
Building target module 2.6 kernel.
PLEASE IGNORE THE "Overriding SUBDIRS" WARNING
make -C /lib/modules/2.6.32-431.el6.i686/build SUBDIRS=/root/kerntest/hello modules

Building modules, stage 2.
MODPOST 1 modules
make[1]: Leaving directory `/usr/src/kernels/2.6.32-431.20.3.el6.i686'
I see the .ko file, but don't see any kernel messages showing the module was activated. I also checked in /lib/modules/2.6.32-431.20.3.el6.i686/extra but there is nothing there. I also tried 'dmesg' and 'lsmod' but didn't see it.
Can anyone point me in the right direction?
I am trying this on CentOS 6.5
You need to actually load the module into the kernel after compiling by using insmod or modprobe :)
I am trying to install QODBC drivers on ubuntu 13.10 for Qt 5.0.2. I have followed the official documentation (see http://qt-project.org/doc/qt-5/sql-driver.html#qodbc) but am stuck at one of the steps. When I try to do
qmake "INCLUDEPATH+=/usr/local/unixODBC/include" "LIBS+=-L/usr/local/unixODBC/lib -lodbc"
it just shows me the help manual for qmake and does nothing.
So I tried to make an empty Makefile and then passed it as an argument
qmake "INCLUDEPATH+=/usr/local/unixODBC/include" "LIBS+=-L/usr/local/unixODBC/lib -lodbc" Makefile
when I try to "make" the generated Makefile, it shows the following errors:
Makefile:183: warning: overriding commands for target `Makefile'
Makefile:130: warning: ignoring old commands for target `Makefile'
make: Circular Makefile <- Makefile dependency dropped.
make: Circular Makefile <- Makefile dependency dropped.
make: Nothing to be done for `first'.
I have just managed to make the odbc driver installation. The main problem here seems to be that you are not including the "pro" target file.
Here all the steps are:
Go to odbc pluggin path. In my case: cd ~/Qt/5.3/Src/qtbase/src/plugins/sqldrivers/odbc
Run qmake including the target LIB paths and also the pro file:
~/Qt/5.3/gcc_64/bin/qmake -makefile "INCLUDEPATH+=/usr/local/include" "LIBS+=-L/usr/local/lib -lodbc" odbc.pro
make and then sudo make install
I hope it will be usefull.
