Eclipse Luna on Mac Yosemite, CDT, XCode7.
HelloWorld with makefile:
- Copied from Eclipse Tutorial main.cpp and makefile for HelloWorld;
- Ran 'Build Project' and got the console:
"
11:39:25 **** Build of configuration Debug for project HelloWorldMakefile ****
make all
Building file: ../main.cpp
Invoking: GCC C++ Compiler
g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"main.d" -MT"main.d" -o "main.o" "../main.cpp"
Finished building: ../main.cpp

Building target: HelloWorldMakefile
Invoking: MacOS X C++ Linker
g++ -o "HelloWorldMakefile" ./main.o
Finished building target: HelloWorldMakefile


11:39:25 Build Finished (took 330ms)
"
- Tried to run Debug, and got the error that 'gdb' cannot run.
Question:
Why no .exe file was built?

1. The run files on OS X are not .exe files, but files without a specific extension.

2. The XCode packege does not use GDB as standard debugger. You have to install it into the system separately.

3. It seems that your run firl has been built under the name HelloWorldMakefile.

Installed GDB with Homebrew, signed the certificate, changed the Run/Debug Configurations, entered the location of GDB in Preferences/C/C++ /Debug/GDB, and voila! It works!
Thank you again, Tauno.

Took me forever to get GDB to couple with eclipse on Catalina. The two sets of instructions I finally end up using that work were:
Configuration: Catalina, Version: 2020-06 (4.16), and GDB 9.1

1) https: (couldn't include a link, so cut/past this to recreate)
//superuser.com/questions/1436370/how-to-codesign-gdb-on-os-x-mojave
2) and when one gets to the "set entitlement" stage, use the root account

Debugging like a pro now, with GDB

I had the same problem when I loaded
Catalina,
Eclipse Version: 2020-06 (4.16)
GDB, 9.1

I finally had to follow these instructions, which weren't all that easy to find, and differ slightly from above. (remove the spaces, as this is my first post and I wast stopped from posting links)

1). https: //superuser.com /questions
/1436370/how-to-codesign-gdb-on-os-x-mojave

2) enable root to set the self-signed-cert & entitlement for GDB
3) disable root after
