I want to debug an application with Eclipse Oxygen on an arm-linux (debian) target where ssh is not installed.
So I used the C/C++ Attach to Application method.
I've compiled the application with g3option of course and copied the application on the target.
I've started gdbserver on the target.
When I start debugging (using the cross gdb of course), it connects to gdbserver via TCP and it stops on the application's start address but it doesn't load the source file.
When I click on resume, the application starts normally.
If I debug it locally, everything works well of course.
What is missing here to get the source files loaded?
What usefull info I can provide to guess what's wrong?
Edit
make all

You need to map the source path in GDB. Have a look here for the documentation.
Finding Source file mapping
You can try running the following command in cross GDB to find the source file mapping:
info sources
# Find the source files used to build the executable.
Mapping the binary source file paths to absolute file paths
For example, if the file /foo/bar/baz.c was moved to /mnt/cross/baz.c, then the command:
set substitute-path /foo/bar /mnt/cross
Note: Referenced from GDB documentation available here.

Unable to find uint8_t despite having build the freestanding libs for C++

Which seems like an easy fix, just add #include <cstdint>, but my file looks like:
#include "inc/kernel.hpp"
#include <cstdint>
void Kernel::kernel_main()
{
uint8_t a;
// nak::print
// nak::input();
}
Which is aggrevating. I know I have the library itself because I see it in my toolchain:
$ find . -name cstdint
./Toolchain/src/gcc-12.2.0/libstdc++-v3/include/tr1/cstdint
./Toolchain/src/gcc-12.2.0/libstdc++-v3/include/c_global/cstdint

And my Toolchain file Toolchain/os-dev-toolchain.cmake looks like:

set(CMAKE_CXX_COMPILER_WORKS 1) # Skip Test because we are in a free-standing environment
set(CMAKE_SYSTEM_PROCESSOR i686)

set(CMAKE_CXX_COMPILER ${CMAKE_SOURCE_DIR}/Toolchain/opt/cross/bin/i686-elf-g++)
And this is how I compile (These arguments are generated with CMake)

So, you see that I'm building with my crosscompiler as per my first argument
/home/jared/projects/cpp_projects/NakOS/Toolchain/opt/cross/bin/i686-elf-g++
I have tried setting sysroot to my toolcahin with:

but no cigar.

I have tried std::uint8_t but that also doesn't work. I got the following error when using that

This is a bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107134 , but in this case, you do not have _GLIBCXX_HAVE_STDINT_H so stdint.h is not included at all, so there are no symbols at all. You can follow this fix https://github.com/gcc-mirror/gcc/commit/7cdab65f3d770345903023f357b6ca96bc85a002 which adds the symbols to cstdint.
So, I need to compile, assemble, and link a C++ file. But, I need to use an external library with it. So, I'm attempting to do so with G++ using this batch file:
g++ -c WindowTest.cpp -I include\bgfx-master\include\bgfx -I include\glfw-3.3.8.bin.WIN32\include\GLFW --verbose
g++ WindowTest.o -o WindowTest.exe -static -L include\glfw-3.3.8.bin.WIN32\lib-vc2022 -l glfw3.lib --verbose
However, when run, I get this output:
g++ -c WindowTest.cpp -I include\bgfx-master\include\bgfx -I include\glfw-3.3.8.bin.WIN32\include\GLFW --verbose
Using built-in specs.

I've tried moving the library file, adding or removing space between the -l option and glfw3.lib, and many other things. It gives this output every time unless I just don't try to include the library file, in which case I get this error:

Question: seems that this complier does not support flag --specs, is it possible in CMake to remove this flag from settings? I think it is added by default..
I managed it to get a working blink template with libopencm3 for the STM32F051 (# stmf0discovory). Then I wanted to get a working one for my Maple Mini (with STM32F103 = cortex-m3) so I copied the first one and changed the cpu flag from cortex-m0-plus to cortex-m3, the library from opencm3_stm32f0 to opencm3_stm32f1 and so on...
But as you can guess its not compiling. From the compilation log it seems like the compiler is not invoking the linker and thats why its not finding the gpio_mode_setup function and definistions like GPIO_MODE_OUTPUT. Here are the Eclipse console outputs:
str32f0 - working:

I am pretty sure its a stupid mistake, but I cant find it by my own and hope you can give me a hint.
Thank you very much.
The libopencm3 library interfaces for the mentioned architectures are different.
For the f1 the function is gpio_set_mode and not gpio_mode_setup. Also the defines are slightly different.
I have installed and built the BOTAN cryptographic library.
Everything seems correctly installed, since I have the following entries in /usr/local/lib directory:
-rw-r--r-- 1 root root 7676350 2012-06-03 11:01 libbotan-1.10.a
lrwxrwxrwx 1 root root 20 2012-06-03 11:01 libbotan-1.10.so -> libbotan-1.10.so.0.1
lrwxrwxrwx 1 root root 20 2012-06-03 11:01 libbotan-1.10.so.0 -> libbotan-1.10.so.0.1
-rwxr-xr-x 1 root root 3396354 2012-06-03 11:01 libbotan-1.10.so.0.1
and in the /usr/local/include one too:
drwxr-xr-x 3 root root 4096 2012-06-03 11:01 botan-1.10
And eventually I managed to include the libraries in the main of my program, and write code without error.
However when building my project (on Eclipse Indigo) I get the following output on console, with the red stderr fashion:
error while loading shared libraries: libbotan-1.10.so.0: cannot open shared object file: No such file or directory
The code I'm trying to execute is the following:
try
{
cout << "In try" << endl;
Botan::LibraryInitializer init;
}catch(std::exception& e)
{
cout << "In catch" << endl;
cerr << e.what() << endl;
}
I have the following doubts:
Is it a problem of the Linker? (And if yes, why isn't the linker throwing the error, but the stderr?)
If not, how can I figure out to let my program find the libbotan-1.10.so.0 file which is actually there? (in /usr/local/lib).
Note that my environment variable $LD_LIBRARY_PATH is currently set, and has the following value:
$> echo $LD_LIBRARY_PATH
$> /usr/local/lib/

**** Build Finished ****
The error is coming at run-time. You need to specify the rpath for the binary at build time - Where you have the:
-L/usr/local/lib
You also need:
-Wl,-rpath=/usr/local/lib
This instructs ld to use this path when trying to find the library at run-time. Your LD_LIBRARY_PATH is probably being overridden by the launcher of eclipse, which is why the variable is not being used.
Alternatives:
Make sure that /usr/local/lib is in the /etc/ld.so.conf, and that ldconfig has been run after installing the library.
Link to the .a, using the command line:
g++ -o "MTVS_oobClient" ./mainOobClient.o ./oobClientClass.o -L/usr/local/lib -Wl,-Bstatic -lbotan-1.10 -Wl,-Bdynamic
or using:
g++ -o "MTVS_oobClient" ./mainOobClient.o ./oobClientClass.o /usr/local/lib/libbotan-1.10.a
... both should have the same effect
Since the program build ends correctly, it is clear that it's a run-time problem due to the fact that the program can't find the Shared Library.
I looked for other people with same run-time issue and found out the solution (that I'll briefly sum up) thanks to another SO question.
What I did was to build the dynamically-linked executable, that wishes to be linked against libbotan-1.10.so.0 at execution time. The linking during the build phase was done with command line option -L/usr/local/lib.
There are a few options to make botan (or any other library) available at run-time:
Create a symlink to botan in a directory listed in /etc/ld.so.conf (or /lib or /usr/lib)
Copy botan to a directory listed in /etc/ld.so.conf (or /lib or /usr/lib) (defaults)
Add the directory containing botan to /etc/ld.so.conf
Set LD_LIBRARY_PATH=/usr/local/lib before running your executable.
Recompile the program statically. (It will work, but don't bother.)
After any of the first 3, rerun ldconfig so the linker cache is updated. (You can then run ldconfig -v to verify it's resolvable.)
Note those aren't steps, they're options. You only need to do 1 of them.
Updating the linker cache with ldconfig made it work for me.
