does it support esp32

[milamber-ls]

how can I run the .\configure so I can compile it for esp32 (esp-idf)?

Hi @milamber-ls,

Have you ever heard of the the process termed "cross-compiling"? To cross compile on one system for another target system you need to acquire the appropriate toolchain that can compile for the target device. Once acquired you can setup a configure like so:

GENERIC EXAMPLE:

./configure \
CC="/path/to/your/toolchain/x-x-x-gcc" \
AR="/path/to/your/toolchain/x-x-x-ar" \
AS="/path/to/your/toolchain/x-x-x-gcc" \
RANLIB="/path/to/your/toolchain/x-x-x-ranlib" \
LD="/path/to/your/toolchain/x-x-x-ld" \
--host=<your host> \
<your other configure options here> \
CFLAGS="-mcpu=<your cpu definition here> \
<other cflags here>" \
LIBS="<libs>"

SPECIFIC EXAMPLE:

./configure \
CC="/usr/local/gcc_arm/gcc-arm-none-eabi-7-2017-q4-major/bin/arm-none-eabi-gcc" \
AR="/usr/local/gcc_arm/gcc-arm-none-eabi-7-2017-q4-major/bin/arm-none-eabi-ar" \
AS="/usr/local/gcc_arm/gcc-arm-none-eabi-7-2017-q4-major/bin/arm-none-eabi-gcc" \
RANLIB="/usr/local/gcc_arm/gcc-arm-none-eabi-7-2017-q4-major/bin/arm-none-eabi-ranlib" \
LD="/usr/local/gcc_arm/gcc-arm-none-eabi-7-2017-q4-major/bin/arm-none-eabi-ld" \
--host=arm-none-eabi \
-enable-aesgcm --enable-ecc \
CFLAGS="-mcpu=cortex-m4 \
-Os -specs=rdimon.specs"  \
LIBS="-Wl,--start-group -lm -lgcc -lc -lrdimon -Wl,--end-group"

yes I have. cross compiling didn't work in esp-idf for windows. I haved installed the Linux version of esp-idf and I managed to successfully execute autogen and configure scripts. then I included them in an esp-idf project and wolfmqtt compiled. I am not sure about if i have set the #defines correcltly but I will figure it out. thank you for sharing this.
