problem linking .so file to code.c

[lin1900]

Hi, I am having problem linking .so file to my main1.c
At first, I used the command below to create .so file from multiple c source and header files.
arm-linux-gnueabi-gcc -shared -o ~/Docs/examples/libmylib1.so -fPIC *.c -lpthread -ldl -lm
Then I created main1.c file in the same folder (~/Docs/examples) and used the following command to generate another .so file for main1.c that uses libmylib1.so
arm-linux-gnueabi-gcc -shared -o libmain2.so main1.c -idirafter ~/Docs/examples -lmylib1 -lpthread -ldl -lm
So far, it worked fine.
But, when I copy the libmylib1.so file to another folder and try to use it with another code.c file it doesn't work unless I add {-idirafter ~/Docs/examples} and let it know the original location of libmylib1.so. The new folder contains only libmylib1.so and code.c. Here is the command that I used and it isn't working.
arm-linux-gnueabi-gcc -shared -o libcode1.so code.c -idirafter ~/Docs/newlocation -lmylib1 -lpthread -ldl -lm
Any suggestions on how to fix this?
Thanks.

Here are some of my attempts:
abc@abc-TULPAR-T5-V21-4:~/Docs/newlocation$ ls
code.c libmylib1.so
abc@abc-TULPAR-T5-V21-4:~/Docs/newlocation$ arm-linux-gnueabi-gcc -shared -o libcode1.so code.c -L ~/Docs/newlocation -lmylib1 -lpthread -ldl -lm
code.c:1:10: fatal error: comm_genlib.h: No such file or directory
1 | #include "comm_genlib.h"
| ^~~~~~~~~~~~~~~
compilation terminated.
abc@abc-TULPAR-T5-V21-4:~/Docs/newlocation$ arm-linux-gnueabi-gcc -shared -o libcode1.so code.c -L ~/Docs/newlocation -idirafter ~/Docs/examples -lmylib1 -lpthread -ldl -lm
abc@abc-TULPAR-T5-V21-4:~/Docs/newlocation$ ls
code.c libcode1.so libmylib1.so
I don't know why it works when I added -idirafter ~/Docs/examples

Header files were missing. I included the header files along with .so file. Now the issue is solved.
