(abstract) Proof is not complete. (assert) r Records declared with the keyword Record or Structure cannot be recursive Refine passed ill-formed term Require inside a module is deprecated and strongly discouraged. You can Require a module at toplevel and optionally Import it inside another one Ring operation should be declared as a morphism s Section variable :n:‘ident’ occurs implicitly in global declaration :n:‘qualid’ present in hypothesis :n:‘ident’ Section variable :n:‘ident’ occurs implicitly in global declaration :n:‘qualid’ present in the conclusion Signature components for label ‘ident’ do not match SProp is disallowed because the "Allow StrictProp" flag is off Stack overflow or segmentation fault happens when working with large numbers in ‘type’ (threshold may vary depending on your system limits and on the command executed) Statement without assumptions Syntax error: [prim:reference] expected after 'Notation' (in [vernac:command]) Syntax error: [prim:reference] expected after [prim:reference] (in [vernac:command]) t Tactic failure Tactic failure (level ‘num’) Tactic failure: fails Tactic failure: succeeds Tactic generated a subgoal identical to the original goal. This happens if ‘term’ does not occur in the goal Tactic Notation ‘qualid’ is deprecated since ‘string’. ‘string’ Tactic ‘qualid’ is deprecated since ‘string’. ‘string’ template and polymorphism not compatible Terms do not have convertible types The 'abstract after' directive has no effect when the parsing function (‘qualid’) targets an option type The / modifier may only occur once The command has not failed! The conclusion is not a substitutive equation The conclusion of ‘type’ is not valid; it must be built from ‘ident’ The constant ‘numeral’ is not a binary64 floating-point value. A closest value will be used and unambiguously printed ‘numeral’. [inexact-float,parsing] The constructor ‘ident’ expects ‘num’ arguments The cumulative and noncumulative attributes can only be used in a polymorphic context The elimination predicate term should be of arity ‘num’ (for non dependent case) or ‘num’ (for dependent case) The field ‘ident’ is missing in ‘qualid’ The file ‘ident’.vo contains library ‘qualid’ and not library ‘qualid’ The recursive argument must be specified The reference is not unfoldable The reference X was not found in the current environment The reference ‘qualid’ was not found in the current environment The term ‘term’ has type ‘type’ which should be Set, Prop or Type The term ‘term’ has type ‘type’ while it is expected to have type ‘type’' The type ‘ident’ must be registered before this construction can be typechecked The variable ‘ident’ is already defined The ‘num’ th argument of ‘ident’ must be ‘ident’ in ‘type’ The ‘term’ provided does not end with an equation There is no flag or option with this name: "‘setting_name’" There is no flag, option or table with this name: "‘setting_name’" There is no qualid-valued table with this name: "‘setting_name’" There is no string-valued table with this name: "‘setting_name’" There is nothing to end This command does not support this attribute This command is just asserting the names of arguments of ‘qualid’. If this is what you want, add ': assert' to silence the warning. If you want to clear implicit arguments, add ': clear implicits'. If you want to clear notation scopes, add ': clear scopes' This object does not support universe names This proof is focused, but cannot be unfocused this way This tactic has more than one success To avoid stack overflow, large numbers in ‘type’ are interpreted as applications of ‘qualid’ Too few occurrences Trying to mask the absolute name ‘qualid’! u Unable to apply Unable to find an instance for the variables ‘ident’…‘ident’ Unable to infer a match predicate Unable to satisfy the rewriting constraints Unable to unify ... with ... Unable to unify ‘term’ with ‘term’ Unbound [value|constructor] X Unbound context identifier ‘ident’ Undeclared universe ‘ident’ Unexpected non-option term ‘term’ while parsing a numeral notation Unexpected non-option term ‘term’ while parsing a string notation Unexpected term ‘term’ while parsing a numeral notation Unexpected term ‘term’ while parsing a string notation Universe inconsistency Universe instance should have length ‘num’ Unknown inductive type Use of ‘string’ Notation is deprecated as it is inconsistent with pattern syntax v Variable ‘ident’ is already declared w When ‘term’ contains more than one non dependent product the tactic lapply only takes into account the first product Wrong bullet ‘bullet’: Bullet ‘bullet’ is mandatory here Wrong bullet ‘bullet’: Current bullet ‘bullet’ is not finished y You should use the “Proof using [...].” syntax instead of “Proof.” to enable skipping this proof which is located inside a section. Give as argument to “Proof using” the list of section variables that are not needed to typecheck the statement but that are required by the proof ‘ ‘class’ must be a transparent constant ‘ident’ cannot be defined ‘ident’ is already declared as a typeclass ‘ident’ is already used ‘ident’ is declared as a local axiom ‘ident’ is not a local definition ‘ident’ is used in conclusion ‘ident’ is used in hypothesis ‘ident’ ‘ident’ is used in the conclusion ‘ident’ is used in the hypothesis ‘ident’ ‘ident’: no such entry ‘qualid’ cannot be used as a hint ‘qualid’ does not occur ‘qualid’ does not respect the uniform inheritance condition ‘qualid’ is already a coercion ‘qualid’ is bound to a notation that does not denote a reference ‘qualid’ is not a function ‘qualid’ is not a module ‘qualid’ is not an inductive type ‘qualid’ not a defined object ‘qualid’ not declared ‘qualid’ should go from Byte.byte or (list Byte.byte) to ‘type’ or (option ‘type’) ‘qualid’ should go from Numeral.int to ‘type’ or (option ‘type’). Instead of Numeral.int, the types Numeral.uint or Z or Int63.int or Numeral.numeral could be used (you may need to require BinNums or Numeral or Int63 first) ‘qualid’ should go from ‘type’ to Byte.byte or (option Byte.byte) or (list Byte.byte) or (option (list Byte.byte)) ‘qualid’ should go from ‘type’ to Numeral.int or (option Numeral.int). Instead of Numeral.int, the types Numeral.uint or Z or Int63.int or Numeral.numeral could be used (you may need to require BinNums or Numeral or Int63 first) ‘type’ is not an inductive type
