understanding C issues in geany install

Show all headers | View raw

Hello NewsGroup,

I can't wrap my head around the C issues that crop up in installing 
geany. When I'm forced back to C, I feel like I've been stripped of my 
rank and sent to Siberia or even relapsed, but those are just feelings, 
and probably an ego manifestation. Quite simply, I've forgotten most of 
what I knew about C, as I would have been most engaged with it whilst on 
MS architecture. I have high hopes for geany, including porting it to 
windholes, so I can use the gf's laptop to script.

I found that the build environment played a huge role in getting code to 
work, and that I wouldn't be able to replicate the frequent posts on 
*nix architecture. The simple fact is, if you are posting C output, then 
it must have run on *some* implementation, so a detractor or an OS bigot 
can claim that it is "implementation-specific" and therefore OT. 
Eschewing MS, one has to be his own IT guy....

Enough with the prologue.

Q1) Does contemporary standard C have any defined relationship to the 
shell, from the point of view of C?

Running ./configure  ...
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... /bin/mkdir -p

Q2) What does -c entail in the above?

Q3) When I script, I write
mkdir -p boulder
, without really knowing why. Is there a place I can look at the C 
source of mkdir on my machine to ascertain why?

$ lsb_release -a
No LSB modules are available.

$

checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables...
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ISO C89... none needed
checking whether gcc understands -c and -o together... yes
checking dependency style of gcc... gcc3
checking how to run the C preprocessor... gcc -E

Nothing crazy looking here. Do I gather correctly that g is an alias for 
gcc?

Also, curious how C 89 and 99 were made to gyve:
checking for gcc option to accept ISO C99... none needed

checking if gcc static flag -static works... yes
checking if gcc supports -c -o file.o... yes
checking if gcc supports -c -o file.o... (cached) yes

Again, cloudy about -c in this context.

Finally, I have one Big Question:

Does the C Programming Language, as defined by C99, define anything 
about the shells that surround it? It's alright if the answer is no; I 
just want to know what it is.

 From C's point of view, what is bash? Does bash have a standard it 
adheres to? Is that POSIX?

Thanks for your comment. It's nice to "see old faces." I won't stick 
around too long if you just answer my questions.
