[Solved] A compilation error about mbedtls

Added by ouyang.wei.victor 4 months ago

When I tried to compile lighttpd with mbedtls 3.2.0, the following error occurred

configure:18214: /arm-x86-sysroots/i686-linux/usr/bin/arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc -o conftest  -std=c11 -fPIC -I/home/o99130/mbedtls/output/include -I/arm-x86-sysroots/acp-am335x-cpm3/usr/include -I/home/o99130/work/sic-or/3rdparty/misc/lighttpd/lighttpd-1.4.73/../../../openlib/pcre2/lib/../include  -I/arm-x86-sysroots/acp-am335x-cpm3-13-3-LCD/usr/include -I/arm-x86-sysroots/acp-am335x-cpm3/usr/include/c++/4.9.1 -I/arm-x86-sysroots/acp-am335x-cpm3/usr/include/c++/4.9.1/arm-linux-gnueabihf --sysroot=/arm-x86-sysroots/acp-am335x-cpm3  -D_REENTRANT -I/home/o99130/mbedtls/output//include -fPIC -L/arm-x86-sysroots/acp-am335x-cpm3/usr/lib -L/home/o99130/mbedtls/output/lib/ -L/home/o99130/work/sic-or/3rdparty/misc/lighttpd/lighttpd-1.4.73/../../../openlib/pcre2/lib/ --sysroot=/arm-x86-sysroots/acp-am335x-cpm3 -L/home/o99130/mbedtls/output//lib conftest.c -lmbedtls -lmbedcrypto -ldl   >&5

The error output indicates that libmbedtls.so depends on libmbedx509.so. However, the configure file test compilation environment does not link to libmbedx509.so. Change line 18189 to 

LIBS="-lmbedtls -lmbedx509 -lmbedcrypto "$DL_LIB" $LIBS"

Compilation passed.Hope it helps people who have the same problem as me.
