使用 64 位扩展编译 disksim4 时出现 Linker 错误

Question

I'm trying to compile the Disksim4 simulator with dixtrac. I've followed the instructions from here: http://cighao.com/2016/03/23/disksim-with-ssdmodel-source-analysis-013-use-it-on-64bit/ to install the SSD patch along with the 2 patches recommended on that page.

All the required files compile (however with many warnings about implicit function declarations). However, it fails at the following command:

gcc -Wall -Wno-unused -MD -I. -I../diskmodel/include -I../libparam/include -I../libddbg/include -g -DASSERTS   -I../memsmodel/include -I../ssdmodel/include -D_INLINE  -o disksim disksim_main.o -L. -ldisksim -L../diskmodel/lib -ldiskmodel -L../memsmodel/lib -lmemsmodel -L../ssdmodel/lib -lssdmodel -L../libparam/lib -lparam -L../libddbg/lib -lddbg -lm

For example,

./libdisksim.a(disksim.o): In function `addlisttoextraq': /home/karthik/school/disksim-4.0/src/disksim.c:235: undefined reference to `addtoextraq'

All the errors are similar to the one above. Not sure how to proceed to fix this. If anyone is familiar with this and has any suggestions, I would greatly appreciate it! thank you!

This error comes from the higher version of GCC. I've seen this error too when I try to make in the disksim-4.0 directory using GCC-10 and GCC-9. After searching a lot of information, finally I found that it is the version of GCC that causes this error.

Switch to a lower version of GCC (I switched to GCC-4.9), then just make in the disksim-4.0 directory as above. Now you can successfully compile disksim-4.0!

If you do not know how to install a lower version of GCC, here is the link: Install lower version of GCC .

Also, here is the link that tells you how to install multiple versions of GCC in your Linux and the way to switch between them: How to switch between multiple GCC and G++ compiler versions on Ubuntu 20.04 LTS .

FYI.
