Hey gang, Got the below error when building httpd from source on a bare metal Intel Core i7-2600 with 4 CPUs.
Ran the identical command on a virtualized AMD EPYC without issue. And, was also able to copy and run successfully the resultant httpd binary from the AMD EPYC on the Core i7. For the record, I used _the same_ src.tar.gz and sys.tar.gz files on both machines. Both machines produce identical sha512s of those two files. Both machines began life at 7.3 and have been tracking official releases / patches / upgrades since 7.3 and have been updated / upgraded in a timely fashion using sysupdate / sysupgrade. Here are the steps that caused the error: # cd /usr/src/usr.sbin/httpd # make clean rm -f a.out [Ee]rrs mklog *.core y.tab.h httpd parse.o config.o control.o httpd.o log.o logger.o proc.o server.o server_http.o server_file.o server_fcgi.o patterns.o parse.c css.h js.h parse.d config.d control.d httpd.d log.d logger.d proc.d server.d server_http.d server_file.d server_fcgi.d patterns.d # make obj /usr/src/usr.sbin/httpd/obj -> /usr/obj/usr.sbin/httpd # make yacc -o parse.c /usr/src/usr.sbin/httpd/parse.y cc -O2 -pipe -Wall -I/usr/src/usr.sbin/httpd -I/usr/src/usr.sbin/httpd/obj -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wshadow -Wpointer-arith -Wsign-compare -Wcast-qual -Werror-implicit-function-declaration -MD -MP -c parse.c cc -O2 -pipe -Wall -I/usr/src/usr.sbin/httpd -I/usr/src/usr.sbin/httpd/obj -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wshadow -Wpointer-arith -Wsign-compare -Wcast-qual -Werror-implicit-function-declaration -MD -MP -c /usr/src/usr.sbin/httpd/config.c /usr/src/usr.sbin/httpd/config.c:638:7: error: call to undeclared function 'imsg_get_fd'; ISO C99 and later do not support implicit function declarations [-Werror,-Wimplicit-function-declaration] fd = imsg_get_fd(imsg); ^ /usr/src/usr.sbin/httpd/config.c:638:7: note: did you mean 'imsg_get'? /usr/include/imsg.h:116:10: note: 'imsg_get' declared here ssize_t imsg_get(struct imsgbuf *, struct imsg *); ^ 1 error generated. *** Error 1 in /usr/src/usr.sbin/httpd (<sys.mk>:87 'config.o') Here's the dmesg from the Intel: OpenBSD 7.5 (GENERIC.MP) #82: Wed Mar 20 15:48:40 MDT 2024 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 17085018112 (16293MB) avail mem = 16546058240 (15779MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.6 @ 0xeb1d0 (104 entries) bios0: vendor American Megatrends Inc. version "9005" date 09/18/2018 bios0: ASUSTeK COMPUTER INC.
