[rtl] Many .O files to one loadable .O module with GCC?
To [EMAIL PROTECTED] We are using Red Hat 6.1 on a pentium 233 Mhz with Linux version 2.2.14-rtl2.2 (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #4 Sat May 20 08:52:04 CDT 2000 We are hoping to build a single loadable (INSMOD module compatible) object module for RTLinux. The project consists of many ( 50) .C files and associated .H files. We plan to use MAKE to compile each .C + .H file separately to a .O file then build the final .O loadable module from all the individual .O files. We can't figure out how to get GCC to accept a number of .O files and create a single .O file that can be loaded into RTLinux with INSMOD. Can anyone suggest how we can build a single .O loadable module from many .O files that were individually compiled using GCC? ___ Shel Hoffman St. Louis, MO 63132 USA (314) 993-6132 voice (314) 993-3316 fax [EMAIL PROTECTED] -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl Your_email" | mail [EMAIL PROTECTED] --- For more information on Real-Time Linux see: http://www.rtlinux.org/rtlinux/
Re: [rtl] Many .O files to one loadable .O module with GCC?
Why don't you peek the Rules.make of kernel source package ? You can use 'ld' to make a single loadable object from many 'o' files. Let me give you an example. If you are trying to build a module named 'mymodule.o' with 'object1.o', 'object2.o', and 'object3.o' then the following command can be used. ld -r -o module.o object1.o object2.o object3.o Bye. - Original Message - From: "Sheldon Hoffman" [EMAIL PROTECTED] To: "rtlinux" [EMAIL PROTECTED] Sent: Wednesday, June 07, 2000 8:12 AM Subject: [rtl] Many .O files to one loadable .O module with GCC?

Looking at the output of 'make modules' while compiling a kernel and watching the details really helps. The sound drivers are especially useful. dave... -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl Your_email" | mail [EMAIL PROTECTED] --- For more information on Real-Time Linux see: http://www.rtlinux.org/rtlinux/
