%s: sorry, in-memory destination manager was not compiled in

Error message

%s: sorry, in-memory destination manager was not compiled in

What it means

cjpeg was built without an in-memory destination manager. This feature is present when JPEG_LIB_VERSION >= 80 OR MEM_SRCDST_SUPPORTED is defined. The -memdst switch (which makes cjpeg write to an in-memory buffer instead of a file/stdout) is therefore unavailable; cjpeg prints this message and exits with EXIT_FAILURE.

Solutions

Drop -memdst and write to a file or stdout instead.
Upgrade to libjpeg >= 80 (e.g. libjpeg-turbo/mozjpeg), or rebuild with MEM_SRCDST_SUPPORTED defined, if in-memory output is required.

Example fix

# before
cjpeg -memdst in.ppm

# after
cjpeg in.ppm > out.jpg

Defensive patterns

Strategy: fallback

Validate before calling

# Probe in-memory destination support before using -memdst.
if cjpeg -h 2>&1 | grep -q memdst; then
  MEMDST=-memdst
else
  MEMDST=   # fall back to file/stdout output
fi
cjpeg $MEMDST in.ppm > out.jpg

Prevention

Do not assume -memdst is available on older libjpeg (<80) builds.
Upgrade to libjpeg >= 80 or rebuild with MEM_SRCDST_SUPPORTED if in-memory output is required.

When it happens

Trigger: Invoking `cjpeg -memdst ...` against a libjpeg older than version 80 that was also not built with MEM_SRCDST_SUPPORTED.

Common situations: Embedded or legacy libjpeg builds below v8; vendor SDKs shipping an older libjpeg; toolchains that disable memory source/destination managers.
