# If you want to compile PCRE for a non-Unix system, note that it consists
|
| 7 |
# entirely of code written in Standard C, and so should compile successfully
|
| 8 |
# using normal compiling commands to do the following:
|
| 9 |
#
|
| 10 |
# (1) Compile dftables.c as a stand-alone program, and then run it with
|
| 11 |
# output sent to chartables.c. This generates a set of standard character
|
| 12 |
# tables.
|
| 13 |
#
|
| 14 |
# (2) Compile maketables.c, get.c, study.c and pcre.c and link them all
|
| 15 |
# together. This is the pcre library (chartables.c gets included by means of
|
| 16 |
# an #include directive).
|
| 17 |
#
|
| 18 |
# (3) Compile pcreposix.c and link it as the pcreposix library.
|
| 19 |
#
|
| 20 |
# (4) Compile the test program pcretest.c. This needs the functions in the
|
| 21 |
# pcre and pcreposix libraries when linking.
|
| 22 |
#
|
| 23 |
# (5) Run pcretest on the testinput files, and check that the output matches
|
| 24 |
# the corresponding testoutput files. You must use the -i option with
|
| 25 |
# testinput2.
