Thanks. I had a look into config.log. After the checking
configure:7623: checking for gnum4
there are the 3 sections ## Output variables. ##, ## File substitutions.
## and ## confdefs.h. ##. The last section ends as follows:
## ----------- ##
## confdefs.h. ##
## ----------- ##
/* confdefs.h */
#define PACKAGE_NAME ""
#define PACKAGE_TARNAME ""
#define PACKAGE_VERSION ""
#define PACKAGE_STRING ""
#define PACKAGE_BUGREPORT ""
#define PACKAGE_URL ""
#define LT_OBJDIR ".libs/"
configure: caught signal 2
configure: exit 1
which are the last lines of "config.log". I detected though an earlier
error message in the following lines
configure:5706: gcc -c -g -O2 conftest.c >&5" :
conftest.c: In function 'main':
conftest.c:16:5: error: 'choke' undeclared (first use in this function)
conftest.c:16:5: note: each undeclared identifier is reported only once
for each function it appears in
conftest.c:16:11: error: expected ';' before 'me'
configure:5706: $? = 1
configure: failed program was:
| /* confdefs.h */
| #define PACKAGE_NAME ""
| #define PACKAGE_TARNAME ""

| #define PACKAGE_URL ""
| #define LT_OBJDIR ".libs/"
| /* end confdefs.h. */
| #include "ppl_c.h"

| main ()
| {
|
| #if PPL_VERSION_MAJOR != 0 || PPL_VERSION_MINOR < 11
| choke me
| #endif
|
| ;
| return 0;
| }
configure:5710: result: no
configure:7008: checking for default BUILD_CONFIG
I did not find any other errors in config.log.
I searched for files "ppl_c.h", "conftest.c" and "confdefs.h" in
C:\cygwin folder, and I could find "ppl_c.h", "confdefs.h" (the latter
only when running ./configure and with the same content as in the output
above), but I could not find any file named "conftest.c".
I am not sure if this is related (not much experience on installing in
linux/unix/cygwin), but I have ppl and ppl-dev installed, version
0.10.2-1. According to "ppl_c.h" and my installation, it seems my major
version of ppl is 0 and the minor version is 10. Can this be a problem
for building gdb?

Hello,
I would like to patch my current version of gdb (7.5.50.20120815-cvs
(cygwin-special)) on a cygwin 1.7.17-1 installation.
Prior to that, I tried to build the original gdb sources, which I
downloaded using setup.exe and selecting them.
Without modifying any source code of gdb, I run ./configure from my
source folder:
C:\cygwin\usr\src\gdb-7.5.50-1
After a set of checks, configure hangs at the gnum4 check, at least
more than 2 hours.
I've never seen this exact error, but my first step in diagnosing
configure issues is to check config.log for anomalies.
Also, you're not supposed to configure gdb in /under the directory
containing its own sources. Try creating a "gdb-obj" somewhere else
and then ../gdb-src/configure
I also tried to run ./configure from the gdb folder
(C:\cygwin\usr\src\gdb-7.5.50-1\gdb), but in this case, after a
longer output, configure gives the following error message:
"checking for Tcl private headers... configure: error: could not find
private Tcl headers"
You probably need to install some tcl*-dev package.
