Using code::blocks w/o a project

[Pecan]

But notice that your compiler is acting differently from mine.
Is your bash script outputing to a different location than CB expects?

[dukester]

I don't use a bash script. My default shell is zsh, but I set C::B to use bash thinking that maybe it didn't play nice with zsh or visa-versa!

[Pecan]

Check, that on output, the .o file is sitting in the same dir as the .c file.
You don't get the option of moving the .o or executable when not using a project.

[dukester]

OK - will do!

C::B is not cranking out a `.o' file at all or `gcc' I should say!
What gives?

[Pecan]

Right click on Build log tab and copy paste here.
The same for the Build messages.

You're using a project? The Debug target?

I thought we were working on NO project builds.
Lets simplfy. Start over and use only the build process I used.
We can get to projects a little later.

I want to know that a no-project plan works first.

[dukester]

You bet! Sorry about that ...

[Pecan]

Is there an actual HelloWorld.o sitting in the source dir along wth HelloWold.c ?

[dukester]

~/programming/c/code/temp
ls -al HelloWorld.*
-rw-r--r-- 1 dnormandin dnormandin 161 Jan 28 15:18 HelloWorld.c

find ${HOME} -name HelloWorld.o -print

[Pecan]

Ok, so the compiler is acting up.
Lets get rid of those extra compiler settings.

In your compiler settings, uncheck
-std=c99 -m64 -Og -O2
from both the compiler and the linker options.
until you don't see them in the logs.

[dukester]

Whoa! I just copied the gcc instructions issued by C::B (from the Build Log output) - and pasted into the /temp directory where HelloWorld.c lives. No probs - I've now got a HelloWorld.o file.

I'll run the 2nd gcc line and I bet I'll get an executable.

[dukester]

Nope! I got a linking error:

gcc  -o /home/dnormandin/programming/c/code/temp/HelloWorld /home/dnormandin/programming/c/code/temp/HelloWorld.o  -O2 -m64
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/10/../../../x86_64-linux-gnu/Scrt1.o: in function `_start':

[Pecan]

There something weird in your build log.

What is that line that begins with "/usr/bin/bash". What the heck is that??
Look at my Build log. there are only two lines. And nothing to do with bash. That line is wiping out your .o file.
