Can you please provide me more explanation on the following lines?

>> -Wall -O3 -g -I/export/home/LSS_TOOLS/TOM/libtomcrypt-1.16/src/headers

This is as much as I understand - and please correct me if I am wrong - "-Wall -03 -g" displays all warnings at level 3 of all warnings/errors during the debuging process that is executed when Make builds the create_tilt_heading target. If -g was removed from this command, then would that stop all warnings/errors from being displayed? And what is the significance of the -I include statement; is that where the header files of DOTH is supposed to be stored, and the "src" folder in that path where the source files for those header files supposed to be stored for the command to find the files that need to be compiled? And should that "export" folder be in the same folder as where my Makefile is stored? Does all my .c files belong in the "src" folder or can it also exsist in the same folder with my Makefile? And where should I put my .l file?

>> -L/usr/local/lib
I know that -L is to shcek symlink times, but it is not clear to me why it is needed. Also, exactly what type of files should be stored in lib... or why does it need this command?

>> -L/export/home/LSS_TOOLS/TOM/libtomcrypt-1.16
Is this just another path that has files that the command "-Wall -03 -g" needs to compile to create the target?

>>lfl -lm -ltomcrypt
I think this has something to do with flex, but still not clear how it is used or it's purpose. Please exlpain further.

I am trying to take someone else's code that was designed to run on Linux, and I am moving it to run on a Windows XP computer with Cygwin. I am having trouble getting the Makefile to complete the process due to an "undeclared identifier" and I was thinking it is because the files are not in a location where the Makefile can find them.

The libtomcrypt library is supposed to build into another set of C code that uses the libtomcrypt. Are you familiar with libtomcrypt?

>>tells gcc to look in /export/home/LSS_TOOLS/TOM/libtomcrypt-1.16/src/headers for files mentined in #include lines (as well as the usual place /usr/include)

Does this mean that as long as all the header files of "DOTH" (or all the projects .C files that have include <xxxx.h> and include "xxxx.h" in the code) are stored in /usr/include, then I don't need to store them in /export/home/LSS_TOOLS/TOM/libtomcrypt-1.16/src/headers anymore? The header files that need to be included in these locations, are they only limited to the files associated with the target or should I put all of the projects header files in the specified location?

What about the DOTL = scan_params_file.l; where is this file supposed to go?

What do you mean by "configure script"? This program ran under Linux but I don't know if it ever ran on Cygwin; but I am currently trying to run it on a Windows XP computer with Cygwin installed.

If you copied the package from Linux, did you run "make distclean" first?

$ make distclean
make: *** No rule to make target `distclean'. Stop.

$ make clean
rm -f *.[o]

After the "make clean", running make still gives me the same error.

I am trying to build a package that takes in data from an external Hard-drive and decrypts the data so it can be analyzed on Matlab.

I added the include lines into scan_params_file.l just as you recommended as shown below but didn't work, why?

So I then replace INT_MAX and now it works, but now I am getting another error when I run "make"; it looks like the error occurs when the make gets to the sub-target "make create_tile_heading". Why am I getting this error if "TOMCRYPT = /export/home/TOOLS/TOM/libtomcrypt-1.16" is declared in my Makefile and the path exists on my computer?

$ ldconfig -p|grep tomcrypt
bash: ldconfig: command not found

Can you please tell me more about the compiled package? I think I may need more help with this.

ASKER

I installed all packages that Cygwin offers using their Setup.exe version 2.573.2.2 and selected from one of their downloading URL sites. I couldn't find a linker. I don't think Cygwin offers the command for "ldconfig".

So, which way is the hard way?

Ok, I did a "make" for libtomcrypt-1.17 as you specified and made 1.16 1o 1.17 change in my Makefile, But still getting the same error when I "make" my Makefile. Why wouldn't it create libtomcrypt.a in /lib?

Thanks for the help. I got the program working. I was actually waiting for a response from the EE community because I would like to give everyone more points than splitting just 500 pts. I want to wait another day to hear back from them. If I don't, I guess I will just have to split the 500pts.
