Hello, trying to build dropbear as part of a ptxdist based embedded BSP for an armv5te target, more precisely I try to upgrade dropbear from 2020.81 to 2022.82, the previous version builds fine, the new one fails to build.
Cross toolchain is OSELAS.Toolchain-2016.06.1/arm-v5te-linux-gnueabi/ gcc-5.4.0-glibc-2.23-binutils-2.26-kernel-4.6-sanitized According to config.log … Invocation command line was $ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var -- libdir=/usr/lib --build=x86_64-host-linux-gnu --host=arm-v5te-linux-gnueabi -- enable-harden --enable-largefile --disable-zlib --disable-pam --enable-openpty --enable-syslog --enable-shadow --disable-plugin --disable-fuzz --enable- bundled-libtom --disable-lastlog --disable-utmp --disable-utmpx --disable-wtmp --disable-wtmpx --disable-loginfunc --disable-pututline --disable-pututxline And localoptions.h was set to this: /* localoptions.h created by ptxdist */ #define DROPBEAR_X11FWD 0 #define DROPBEAR_CLI_LOCALTCPFWD 1 #define DROPBEAR_CLI_REMOTETCPFWD 1 #define DROPBEAR_SVR_LOCALTCPFWD 1 #define DROPBEAR_SVR_REMOTETCPFWD 1 #define DROPBEAR_SVR_AGENTFWD 0 #define DROPBEAR_CLI_AGENTFWD 0 #define DROPBEAR_AES128 1 #define DROPBEAR_3DES 0 #define DROPBEAR_AES256 1 #define DROPBEAR_ENABLE_CBC_MODE 0 #define DROPBEAR_ENABLE_CTR_MODE 1 #define DROPBEAR_SHA1_HMAC 0 #define DROPBEAR_DH_GROUP1 0 #define DROPBEAR_DH_GROUP14_SHA1 0 #define DROPBEAR_SHA1_96_HMAC 0 #define DROPBEAR_SHA2_256_HMAC 1 #define DROPBEAR_SHA2_512_HMAC 1 #define DROPBEAR_DSS 0 #define DROPBEAR_RSA 1 #define DROPBEAR_ECDSA 0 #define DROPBEAR_ECDH 0 #define DROPBEAR_CURVE25519 0 #define DROPBEAR_SVR_PASSWORD_AUTH 1 #define DROPBEAR_CLI_PASSWORD_AUTH 1 #define DROPBEAR_SVR_PUBKEY_AUTH 1 #define DROPBEAR_CLI_PUBKEY_AUTH 1 The compile error is like this: arm-v5te-linux-gnueabi-gcc -c -Os -W -Wall -Wno-pointer-sign -fno-strict- overflow -fPIE -fstack-protector-strong -D_FORTIFY_SOURCE=2 -I./libtomcrypt/ src/headers/ -DLOCALOPTIONS_H_EXISTS -I. -I. -DDROPBEAR_SERVER - DDROPBEAR_CLIENT signkey.c -o signkey.o In file included from signkey.c:31:0: sk-ecdsa.h:11:44: error: unknown type name 'ecc_key' signkey.c: In function 'buf_get_pub_key': signkey.c:318:17: error: 'DROPBEAR_SIGNKEY_SK_ECDSA_NISTP256' undeclared (first use in this function) signkey.c:318:17: note: each undeclared identifier is reported only once for each function it appears in signkey.c: In function 'buf_verify': signkey.c:688:17: error: 'DROPBEAR_SIGNKEY_SK_ECDSA_NISTP256' undeclared (first use in this function) signkey.c:689:3: error: unknown type name 'ecc_key' signkey.c:689:20: error: 'ecc_key' undeclared (first use in this function) signkey.c:689:29: error: expected expression before ')' token make[1]: *** [Makefile:154: signkey.o] Error 1 I looked into the dropbear code, and sk-ecdsa.h includes "includes.h" which itself includes "tomcrypt.h" and in some file of that 'ecc_key' is defined, so I don't know why the compiler complains here. Did not look into the other errors however. Any ideas? Greets Alex
