Openwrt dependency cannot be found

Openwrt report library not found
Package * is missing dependencies for the following libraries:
Libc. so.6 or others
First check whether there is any inventory in the system. If not, install it (in/lib/lib64 and other directories)
Then add the compiling environment of the library openwrt.
Different libc. Provides platforms may have different directories. Find./stagging_dir-name libc. Provides
Generally in stagging_dir/target-mipsel_r2_uClibc-0.9.33.2/pkginfo/libc. Provides
Add at the bottom
Libc. so.6
Or other required libraries, so will be converted into the library of the openwrt platform during compilation.
Finally, add the dependency in the makefile of the corresponding openwrt.

If not, use

Added in define package/SC/install

$ (CP)/Your Lib. So $ (1)/usr/bin/

Or...

Makefile example of openwrt

Include $ (topdir)/rules. mkinclude $ (include_dir)/kernel. MK # Your package name pkg_name: = scpkg_release: = 1pkg_build_dir: = $ (build_dir)/$ (pkg_name) include $ (include_dir)/package.

Generally, the written code is stored in/Your openwrt source/package /.

Create a directory, such as SC. The directory structure is as follows:

Package/SC

Package/SC/makefile (the file above)

Package/SC/src/Your. c

Package/SC/src/makefile

Package/SC/src/... # other files

Run sudo make menuconfig to find the definition of section and category in define package/SC.

Note: In your makefile, do not use GCC to use $ (CC); otherwise, it cannot be compiled ..

Makefile example:

SC: SC. o $ (CC) SC. o-o SC-lpthread-lpcapsc. o: SC. c SC. h $ (CC)-c SC. cclean: Rm-RF *. O SC

The front is tab subtraction, and non-space... $ (CC) must not be replaced by GCC...
