don't get echoserver static

[divinity76]

i tried to get echoserver static, but it didn't work, any idea why?

I did basically exactly:

#!/bin/bash
set -euxo pipefail

git clone  --depth 1 'https://github.com/wolfSSL/wolfssh.git'

cd wolfssh

git clone 'https://github.com/wolfSSL/wolfssl.git' --depth 1

cd wolfssl

mkdir install

./autogen.sh

CFLAGS='-s -Os' CXXFLAGS='-s -Os' ./configure --enable-static --disable-shared --prefix="$(pwd)/install" --enable-psa-lib-static

CFLAGS='-s -Os' CXXFLAGS='-s -Os' make -j$(nproc)

make install

cd ..

wget -O- 'https://github.com/wolfSSL/wolfssh/pull/848.diff' | git apply -

mkdir install

./autogen.sh

CFLAGS='-s -Os' ./configure --enable-static --disable-shared --enable-scp --enable-sftp --enable-shell --enable-cryptonly --with-wolfssl=wolfssl/install/ --prefix="$(pwd)/install"

CFLAGS='-s -Os' make -j$(nproc)

make install

(ps had to apply PR #848 to get it to compile)

and then...

$ ldd examples/echoserver/echoserver
	linux-vdso.so.1 (0x00007ffff7fc3000)
	libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007ffff7e1a000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007ffff7c00000)
	/lib64/ld-linux-x86-64.so.2 (0x00007ffff7fc5000)

it's not static. any suggestions?

Hello @divinity76

Thanks for contacting wolfSSL Support. Could you tell us a bit about your project?

The example does use external libs. The math lib dependency can be removed by configuring wolfSSL:

#if 1
    /* Use table for DH instead of -lm (math) lib dependency */
    #if 1
        #define WOLFSSL_DH_CONST
        #define HAVE_FFDHE_2048
        //#define HAVE_FFDHE_4096
        //#define HAVE_FFDHE_6144
        //#define HAVE_FFDHE_8192
    #endif
#else
    #define NO_DH
#endif

The C lib and other dependencies will require you to build those libs as static and modify the make file to use those static libs. This would be more common in an embedded library context. You are building the defaults in linux, so the shared libs are being pulled in.

Let us know if you have further questions.

Thanks,
