Need help cross-compiling OPENSSL for five different targets, each running the QNX operating system

Williams, Roger roger.williams at

The cross-compilation will be performed on a server running:

    Linux Splinter 2.6.32-5-686 #1 SMP Tue May 13 16:33:32 UTC 2014 i686 GNU/Linux

The 5 targets I need to make for are:

  1.  QNX 6.5.0, PPCBE-SPE
  2.  QNX 6.5.0, PPCBE
  3.  QNX 6.5.0, X86
  4.  QNX 6.3.2, PPCBE
  5.  QNX 6.3.2, X86

The compiler (script) used to do the cross compile is qcc99:

    #! /bin/sh
    qcc -Wc,-std=gnu99 "$@"

The configuration settings used for SSH for the same 5 targets are:

  1.  QNX 6.5.0, PPCBE-SPE:

./configure --with-privsep-user=sshd --host=powerpc-unknown-nto-qnx6.5.0 --build=x86 --prefix=   CC='qcc99 -V4.4.2,gcc_ntoppcbespe' CPPFLAGS="-I$HOME/qnx650-ppcbespe/include -D_XOPEN_SOURCE=600 -D_QNX_SOURCE" CFLAGS='-g -O2 -me500v2' LDFLAGS="-L$HOME/qnx650-ppcbespe/lib -static"

  1.  QNX 6.5.0, PPCBE

./configure --with-privsep-user=sshd --host=powerpc-unknown-nto-qnx6.5.0 --build=x86 --prefix=   CC='qcc99 -V4.4.2,gcc_ntoppcbe' CPPFLAGS="-I$HOME/qnx650-ppcbe/include -D_XOPEN_SOURCE=600 -D_QNX_SOURCE" CFLAGS='-g -O2' LDFLAGS="-L$HOME/qnx650-ppcbe/lib -static"

  1.  QNX 6.5.0, X86:

./configure --with-privsep-user=sshd --host=i486-pc-nto-qnx6.5.0 --build=x86 --prefix=   CC='qcc99 -V4.4.2,gcc_ntox86' CPPFLAGS="-I$HOME/qnx650-x86/include -D_XOPEN_SOURCE=600 -D_QNX_SOURCE" CFLAGS='-g -O2' LDFLAGS="-L$HOME/qnx650-x86/lib -static"

  1.  QNX 6.3.2, PPCBE:

./configure --with-privsep-user=sshd --host=powerpc-unknown-nto-qnx6.3.0 --build=x86 --prefix=   CC='qcc99 -V3.3.5,gcc_ntoppcbe' CPPFLAGS="-I$HOME/qnx632-ppcbe/include -D_XOPEN_SOURCE=600 -D_QNX_SOURCE" CFLAGS='-g -O2' LDFLAGS="-L$HOME/qnx632-ppcbe/lib -static"

  1.  QNX 6.3.2, X86:

./configure --with-privsep-user=sshd --host=i386-pc-nto-qnx6.3.0 --build=x86 --prefix=   CC='qcc99 -V3.3.5,gcc_ntox86' CPPFLAGS="-I$HOME/qnx632-x86/include -D_XOPEN_SOURCE=600 -D_QNX_SOURCE" CFLAGS='-g -O2' LDFLAGS="-L$HOME/qnx632-x86/lib -static"

Note that QNX 6.5.0 uses the GCC Version 4.4.2 compiler and QNX 6.3.2 uses the GCC Version 3.3.5 compiler.  In both cases, it is invoked with QCC, not GCC.

I downloaded and tried to make SSH version 8.8.  After configuring it and running make, I eventually get the following error:

qcc99 -V4.4.2,gcc_ntoppcbespe -g -O2 -me500v2 -Wall -Wextra -Wpointer-arith -Wuninitialized -Wsign-compare -Wformat-security -Wno-pointer-sign -Wno-unused-parameter -fno-strict-aliasing -D_FORTIFY_SOURCE=2 -ftrapv -fno-builtin-memset -fstack-protector-all   -fPIC -I. -I.. -I. -I./.. -I/home/williams/ssh/qnx650-ppcbespe/include -D_XOPEN_SOURCE=600 -D_QNX_SOURCE -DHAVE_CONFIG_H -c openssl-compat.c

In response, I downloaded OPENSSL Version 1.1.1l.  I have no idea how to configure this to make it cross-compile for the 5 targets I need the libraries for versus compiling for the server I am compiling on.  If someone can help me configure this for one of the targets, I can manage to do it for the other 4 four.
