Version 6.4 05-Sep-05 |
| 5 |
|
--------------------- |

|
|
| 7 |
|
1. Change 6.0/10/(l) to pcregrep introduced a bug that caused separator lines |
| 8 |
|
"--" to be printed when multiple files were scanned, even when none of the |
| 9 |
|
-A, -B, or -C options were used. This is not compatible with Gnu grep, so I |
| 10 |
|
consider it to be a bug, and have restored the previous behaviour. |
| 11 |
|
|
| 12 |
|
2. A couple of code tidies to get rid of compiler warnings. |
| 13 |
|
|
| 14 |
|
3. The pcretest program used to cheat by referring to symbols in the library |
| 15 |
|
whose names begin with _pcre_. These are internal symbols that are not |
| 16 |
|
really supposed to be visible externally, and in some environments it is |
| 17 |
|
possible to suppress them. The cheating is now confined to including |
| 18 |
|
certain files from the library's source, which is a bit cleaner. |
| 19 |
|
|
| 20 |
|
4. Renamed pcre.in as pcre.h.in to go with pcrecpp.h.in; it also makes the |
| 21 |
|
file's purpose clearer. |
| 22 |
|
|
| 23 |
|
5. Reorganized pcre_ucp_findchar(). |

Version 6.3 15-Aug-05 |
| 27 |
|
--------------------- |
| 28 |
|
|

|
1. The file libpcre.pc.in did not have general read permission in the tarball. |
| 30 |
|
|
| 31 |
|
2. There were some problems when building without C++ support: |
| 32 |
|
|
| 33 |
|
(a) If C++ support was not built, "make install" and "make test" still |
| 34 |
|
tried to test it. |
| 35 |
|
|
| 36 |
|
(b) There were problems when the value of CXX was explicitly set. Some |
| 37 |
|
changes have been made to try to fix these, and ... |
| 38 |
|
|
| 39 |
|
(c) --disable-cpp can now be used to explicitly disable C++ support. |
| 40 |
|
|
| 41 |
|
(d) The use of @CPP_OBJ@ directly caused a blank line preceded by a |
| 42 |
|
backslash in a target when C++ was disabled. This confuses some |
| 43 |
|
versions of "make", apparently. Using an intermediate variable solves |
| 44 |
|
this. (Same for CPP_LOBJ.) |
| 45 |
|
|
| 46 |
|
3. $(LINK_FOR_BUILD) now includes $(CFLAGS_FOR_BUILD) and $(LINK) |
| 47 |
|
(non-Windows) now includes $(CFLAGS) because these flags are sometimes |
| 48 |
|
necessary on certain architectures. |
| 49 |
|
|
| 50 |
|
4. Added a setting of -export-symbols-regex to the link command to remove |
| 51 |
|
those symbols that are exported in the C sense, but actually are local |
| 52 |
|
within the library, and not documented. Their names all begin with |
| 53 |
|
"_pcre_". This is not a perfect job, because (a) we have to except some |
| 54 |
|
symbols that pcretest ("illegally") uses, and (b) the facility isn't always |
| 55 |
|
available (and never for static libraries). I have made a note to try to |
| 56 |
|
find a way round (a) in the future. |
