1. euc build directory and output filename poll

The euc program will compile a Euphoria program to an executable via a C compiler you have available on your system. During this process a lot of C source is generated as well as compiled object files. Thus, to prevent cluttering your working directory, euc offers a command line option -builddir. In this directory is where euc will generate all of it's files necessary for C translation and compilation of your program.

So:

C:\my_program> euc -builddir build myprogram.ex 

will create a directory build and generate a lot of temp stuff there. If everything is a success, the temp stuff is removed. It will leave behind the result which in this case is build\myprogram.exe

euc offers another command line option -o which specifies the name of the output program filename.

So:

C:\my_program> euc -builddir build -o my_program main.ex 

Instead of deriving the executable name from main.ex and creating main.exe euc will use what you specified via -o which is my_program. It does add the executable extension if necessary.

There is a debate between a few dev members on IRC about where the resulting executable should be placed. Should the -o be relative to the -builddir and my_program.exe be placed in C:\my_program\build\my_program.exe or should the -o be relative to the location where euc is run and my_program.exe be placed in C:\my_program\my_program.exe ?

It's all a matter of should -o be relative to -builddir or to where euc is running from.

We want the result of least surprise. If you issued:

C:\my_program> euc -builddir build -o my_program my_program.ex 

Where would you expect to find my_program.exe:

1. C:\my_program\build\my_program.exe
2. C:\my_program\my_program.exe

Thanks for your input.

C:\my_program> euc -builddir build -o c:\some\other\path\my_name my_program.ex 

That would expose a bug that needs to be fixed. It would attempt to write build\C:\some\other\path\my_name. In a similar fashion -build build -o .\program would write build\.\program.

So if an absolute or if the output starts with a . then relative to the current directory, otherwise relative to the build dir is what I understand you'd want Jim, right?

Hi

builddir - where all the build stuff goes, ok.

I would expect the program to output the built program relative to the current dir, not the buildir, unless I specified a path to the output program. So

C:\my_program> euc -builddir build my_program.ex
my_program.exe in c:\my_program

C:\my_program> euc -builddir build -o great_program my_program.ex
great_program.exe in c:\my_program

C:\my_program> euc -builddir build -o c:\goodies\great_program my_program.ex
great_program in c:\goodies

Similarly with linux, current directory first, full path second (with errors issued for permission violations)

Frankly, I think builddir should only be used as the temp directory, and not a default final destination

Another option is to replace -buildir with say -ctemp.

If it helps any, there should be no pressing need to make -buildir stop working, just add the new alternative and change all the docs.

My two cent,

What I would like to see:
The completed .exe file go to the folder the original .exw file is in.

All my uneeded .c files endup in my BIN folder. So I would like to see -e = (erase all .c files created).
