Description Bill McCarty 2002-03-25 13:47:41 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; T312461; Q312461)

Description of problem:
Both /usr/include/sys/types.h and /usr/include/stdint.h unconditionally define 
uint8_t and uint16_t. The former also unconditionally defines uint32_t. This 
causes type redefinition errors when compiling code that uses both include 
files. This affects, for instance, Snort 1.8.4. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Download and attempt to compile snort-1.8.4, available at www.snort.org.

Actual Results:  
gcc -DHAVE_CONFIG_H -I. -I. -I. -I/usr/include/pcap  -I/usr/include  -g -O2 -
In file included from /usr/include/netinet/in.h:23,
                 from snort.h:43,
                 from snort.c:45:
/usr/include/stdint.h:49: redefinition of `uint8_t'
/usr/include/sys/types.h:196: `uint8_t' previously declared here
/usr/include/stdint.h:50: redefinition of `uint16_t'
/usr/include/sys/types.h:197: `uint16_t' previously declared here
/usr/include/stdint.h:52: redefinition of `uint32_t'
/usr/include/sys/types.h:198: `uint32_t' previously declared here
make[2]: *** [snort.o] Error 1
make[2]: Leaving directory `/root/snort-1.8.4'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/root/snort-1.8.4'
make: *** [all-recursive-am] Error 2

Expected Results:  Clean compile.

Additional info:

These include files are included in glibc-devel-2.2.4-19.3, but I don't find 
the glibc-devel component listed. So, I filed under glibc.
Comment 1 Jakub Jelinek 2002-03-25 14:36:48 EST
No, <stdint.h> unconditionally defines uint8_t, uint16_t etc., while
<sys/types.h> unconditionally defines u_int8_t, u_int16_t etc.
The only way how this could happen is if snort defined u_int8_t to uint8_t
before including the headers.
Comment 2 Bill McCarty 2002-03-25 15:05:47 EST
Yes, you're exactly right. Thanks for the keen eyes and mind and the timely 
reply. I'll report this issue to the developers.
