Hello, i'm trying to solve the following situation: building a library which contains some functions and also main(). The goal is, to use this as a framework and link it with a user supplied module which only contains some callback functions. Building up the library is not the problem. Listing it with LIB51 shows: DOS LIBRARY MANAGER LIB51 V4.01 COPYRIGHT KEIL ELEKTRONIK GmbH 1987 - 1997 LIBRARY: MYLIB.LIB >LIB_FUNC >>F_MY_LIB_FUNCTION >LIB_MAIN >>MAIN (>'s added because the forum doesn't support blanks at beginning of line :-) So main() seems to be put in the library as i want it. The problem is linking it with the user supplied module. The linker does not find a root segment. So i tried to add main() as a root segment by specifying overlay(* ! MAIN) as a linker option. But the linker never finds main() at all. Here's my complete linker call: L51 user.obj, mylib.lib to mytest.abs ramsize(256) XD(0000h) overlay(* ! MAIN) It results in: *** WARNING 11: CANNOT FIND SEGMENT OR FUNCTION NAME NAME: MAIN *** WARNING 16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS SEGMENT: ?PR?F_THE_CALLBACK?USER *** WARNING 10: CANNOT DETERMINE ROOT SEGMENT (where F_THE_CALLBACK is a user supplied function called from within main() ) So, even the overlay manager seems not to "see" main. Where's my mistake? Is main() processed different from other functions? Is it impossible to put main() into a library? Thanks in advance for your help. FRANK
Did you put only main() into axmain.obj or is there a collection of several other functions? In the case of putting some other functions into the same object where also main is, I got it working. But I don't understand why it depends on that. Perhaps it's a version issue? Which compiler/linker version do you use? I got C51 v5.50 / L51 v3.70c here. FRANK
Only main(); linker is 3.70 Erik
Strange thing...same linker, same commands, but it doesn't work for me. As a first workaround I will keep main() in an extra obj file, perhaps trying again later to add it to the lib... Thanks for your help! FRANK
PD I am NOT using uVision, because you can not replace the editor with CodeWright, this is DOS commandline. Erik
Erik, Does this mean you're compiling from within CodeWright too? How to you handle projects in CodeWright the way you can do it in uVision? I'm interested in how you manage this all, since I'm also using CodeWright very often for other programming environments, but not for Keil since I don't know how to manage the 'Keil' projects. I would like to know how you have set up your 'IDE' with CodeWright, if possible. --Geert
No IDE, not needed, runnig all from batchfiles. Erik
I use uv2 to create and maintain my projects. Then I configure buttons in CodeWright to build each project. For example, I assign one button to execute this command... c:\keil\uv2\uv2.exe -b -o %v%pvdriver.err %v%pvdriver.uv2 -t "Flash" and I assign another button to execute this command... c:\keil\uv2\uv2.exe -b -o %v%pvdriver.err %v%pvdriver.uv2 -t "Monitor" I also set up the error parser so I can click on the error in CodeWright's output window and it takes me to the appropriate line in the source code. This can all be done in CodeWright's Project Properties dialog box. -Walt
could you please post the howto for CodeWright users I also set up the error parser so I can click on the error in CodeWright's output window and it takes me to the appropriate line in the source code. Even with this posted, I will have a small problem since I do not compile from the source code. In order to maintain 117 projects with various levels of commonality, I "pick and choose" sourcefiles from several places and (while renaming some) combine them into a build directory. Obviously editing in the build directory will not make any changes hold since these files are moved in from elsewhere. I love CodeWright as an editor, but I have one small beef: They have made it so "flexible" that it takes days of reading the manual to find out how to use the flexibility. Fortunetely, I figured out a long time ago with Brief how to set up the editing configurationj. Erik
could you please post the howto for CodeWright users Sure, its the least I can do since it was members of this forum that help me figure out how to do it. http://www.keil.com/forum/docs/thread840.asp I will attempt to put something together today but in the next couple days for sure. It would help if I could include screen shots but I don't think there is anyway for me to do that using this forum. Is it acceptable to those interested to create a pdf and email it to you directly or should I stick to text and post it here? -Walt
Is it acceptable to those interested to create a pdf and email it to you directly absolutely, however or should I stick to text and post it here? If you can post it here with a link to the pdf etc would be even better. Erik
Hi Erik, Let's give this a try. If this doesn't work, I'll email it to you and anyone else that wants it. ftp.crown.com/.../codewright.pdf -Walt
it works well, I'll have a look. Thanx, Erik
