[openssl-users] openssl 1.1.1 cross compile error to vxworks 6.8

[lu zhihong]

Hi，All
Now I am trying build openssl1.1.1 version libs in cross compiler platform(susu12+Vxworks 6.8 ). the build target is vxworks-ppc860.but it failed.
I have tried use different Vxworks versions(such as Vxworks6.4,Vxworks6.8),it still failed.
I want to know if build openssl libs using Vxworks compiler, does it need open some special macro or need take care something? Please help to point out.

The compile issues details messages as follows:
1. h_errno not defined
crypto/bio/b_addr.c: In function 'BIO_lookup_ex':
crypto/bio/b_addr.c:785: error: 'h_errno' undeclared (first use in this function)

2. streams/un.h not found , I can only found sys/un.h
include/internal/sockets.h:76:29: error: streams/un.h: No such file or directory



3. some int type redefined(int8_t, int16_t, int32_t, uint8_t , uint16_t, uint32_t, int64_t, uint64_t) both in stdint.h and vxTypes.h
When first include vxTypes.h then include stdint.h will make this issue

One example:
In include/openssl/crypto.h
First include time.h (time.h -> vxWorks.h-> vxWorksCommon.h-> vxTypes.h)
Then include openssl/e_os2.h(e_os2.h -> stdint.h)

So: In file included from include/openssl/e_os2.h:258,
from include/openssl/crypto.h:17,
from crypto/aes/aes_core.c:42:

Thank you in advance for your help!
