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: Always 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 - Wall -DDEBUG -ggdb -DENABLE_RESPONSE -D_BSD_SOURCE -D__BSD_SOURCE - D__FAVOR_BSD -DHAVE_NET_ETHERNET_H -DLIBNET_LIL_ENDIAN -c snort.c 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.
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.
Yes, you're exactly right. Thanks for the keen eyes and mind and the timely reply. I'll report this issue to the developers.
