Undefined reference error while compiling lzma sdk - c++

Question

while compiling my cpp program for pop os using 7-zip lzma sdk i encounter the following errors
/usr/bin/ld: warning: cannot find entry symbol _start; defaulting to 0000000000001410

here is the script used to compile the program.
run2.sh
for FILE in $(ls "/home/hitesh/lzma2201/C" | egrep '\.c$');
do
g++ -Wall -std=c++14 -g -c -D_7ZIP_ST -I"/home/hitesh/lzma2201/C" "/home/hitesh/lzma2201/C/"$FILE ;

I have tried using another versions of lzma sdk but that was resulting in different errors. I expected the program to run as it was running when i originally wrote the script in .c file for windows
