AR# 58295

描述

I want to use custom libraries in my application, however, when I add a user library (mylib) to the build under Properties > C/C++General > Paths and Symbols > Libraries, this results in an error similar to the following:

c:/xilinx/sdk/2013.2/gnu/arm/nt/bin/../lib/gcc/arm-xilinx-eabi/4.7.2/../../../../arm-xilinx-eabi/bin/ld.exe: cannot find -l-Wl,--start-group,-lmylib,-lxil,-lgcc,-lc,-lstdc++,--end-group
collect2.exe: error: ld returned 1 exit status
make: *** [app_xil_cpu0.elf] Error 1

How can I fix this problem?

解决方案

Adding the library path using the "Add Library" option in "Project Properties -> C/C++ General -> Paths And Symbols -> Libraries" is corrupting the makefile.

Any subsequent changes are effected by this change.

To work around this issue, create a new application and copy the sources from the old application. Then, apply the library settings for the new application by following these steps:

1. Right-click on the application project.
2. Go to C/C++ Build -> Settings.
3. Select "Libraries" section under "Microblaze gcc linker"
4. Press "Add" button and give the library name.
5. Optionally, add the "Library Search Path", if your library is in different path.
