Cross Compiling libgpg-error-1.21 for rsyslog-8.15.0: unrecognized option '--64'.

[Girish Kumar]

Hi All,

I  found  following in README doc. Could you please explain what I should for armv7.
Cross-Compiling
---------------

Libgpg-error needs to figure out some platform specific properties.
These are used to build the platform specific gpg-error.h file.  The
detection is done during build time but can't be done when
cross-compiling.  Thus if you run into an error during building you
need to figure out these values.  You may use these commands:

  build="$(build-aux/config.guess)"
  ./configure --prefix=TARGETDIR --host=TARGET --build=$build
  cd src
  make gen-posix-lock-obj
  scp gen-posix-lock-obj TARGET:
  ssh TARGET ./gen-posix-lock-obj >tmp.h
  mv tmp.h "syscfg/$(awk 'NR==1 {print $2}' tmp.h)"

If you are using a VPATH build adjust accordingly.  If this all works
for you (make sure to run the test programs on the target platform),
please send the generated file to the gnupg-devel mailing list so that
we can include it in the next release.  Note that in addition to the
aliasing done by config.sub the src/mkheader build tool does some
extra aliasing to avoid having too much identical syscfg files.

Girish

Dear All,

I am compiling libgpg-error-1.21 which is a dependency library  for  libgcrypt-1.6.4  . This for armv7 platform
Found some info on cross compilation, but was not able to understand.

I am getting  "unrecognized option '--64'"  when compiling libgpg-error-1.21.  Could you please  help me on this.?
