+fails if it is missing.
+
+* linux/Makefile.am (ccextractor_SOURCES): Add
+../src/lib_ccx/compile_info_real.h.

+Subject: [PATCH] linux/configure.ac: Fix tesseract conditional problem.
+
+For tesseract-ocr's stock pkg-config, it would produce an error due to
+unquoted whitespace:
+
+  $ test ! -z `pkg-config --libs-only-l --silence-errors tesseract`
+  bash: test: syntax error: `-larchive' unexpected
+
+* linux/configure.ac: Use a positive test, and double-quote the $() command
+substitution.
