Hi, udev-147 has its internal bsg.h file removed which leads to an error during compilation when <=sys-kernel/linux-headers-2.6.28-r1 is installed: CC extras/usb_id/usb_id.o extras/scsi_id/scsi_serial.c:31:23: error: linux/bsg.h: No such file or directory extras/scsi_id/scsi_serial.c:156: warning: ‘struct sg_io_v4’ declared inside parameter list extras/scsi_id/scsi_serial.c:156: warning: its scope is only this definition or declaration, which is probably not what you want extras/scsi_id/scsi_serial.c: In function ‘sg_err_category4’: extras/scsi_id/scsi_serial.c:158: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:159: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:159: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:160: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:161: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c: At top level: extras/scsi_id/scsi_serial.c:286: warning: ‘struct sg_io_v4’ declared inside parameter list extras/scsi_id/scsi_serial.c: In function ‘scsi_dump_v4’: extras/scsi_id/scsi_serial.c:288: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:288: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:289: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:297: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:297: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:297: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:300: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:301: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c:302: error: dereferencing pointer to incomplete type extras/scsi_id/scsi_serial.c: In function ‘scsi_inquiry’: extras/scsi_id/scsi_serial.c:328: error: storage size of ‘io_v4’ isn’t known extras/scsi_id/scsi_serial.c:330: error: invalid application of ‘sizeof’ to incomplete type ‘struct sg_io_v4’ extras/scsi_id/scsi_serial.c:332: error: ‘BSG_PROTOCOL_SCSI’ undeclared (first use in this function) extras/scsi_id/scsi_serial.c:332: error: (Each undeclared identifier is reported only once extras/scsi_id/scsi_serial.c:332: error: for each function it appears in.) extras/scsi_id/scsi_serial.c:333: error: ‘BSG_SUB_PROTOCOL_SCSI_CMD’ undeclared (first use in this function) make[2]: *** [extras/scsi_id/scsi_serial.o] Error 1 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 * ERROR: sys-fs/udev-147 failed: Upgrading to >=sys-kernel/linux-headers-2.6.29 is fixing this problem as those versions install bsg.h Reproducible: Always Steps to Reproduce:
According to Kay who removed the file from udev, Kernel >=2.6.23 provide this file. So it seems this is a bug at linux-headers package, that we can ask to be fixed or just depend on >=sys-kernel/linux-headers-2.6.28-r1. I played with latest stable, linux-headers-2.6.27-r2 ebuild and found out: The file bsg.h exists as $S/include/linux/bsg.h, but does not get installed.
that's because linux didnt export it until v2.6.29 commit a229fc61ef0ee3c30fd193beee0eeb87410227f1 Author: Boaz Harrosh <bharrosh@panasas.com> Date: Mon Jan 19 10:37:38 2009 +0100 include/linux: Add bsg.h to the Kernel exported headers so the fact that the kernel has included it since 2.6.23 is terribly relevant if it wasnt exported to userspace until 2.6.29
Added ">=sys-kernel/linux-headers-2.6.29" to DEPEND.
